The Parker 51s shown below were first listed as part of the 2008 "World's Largest Parker 51 Offering".  Some remain. I have hundreds of similar Parker 51s at home, not listed. Feel free to ask.  Please note that this website has no sales cart. Most pens shown are singletons, and I sometimes lag with updates noting completed sales.   Please contact me to confirm availability. Payment typically is by Paypal, though Postal Money Order can be done too. Shipping starts at about $9 insured in USA and ranges up with price of pen. International shipping tends to run $25-$50




December  '08 Update: Focus on Parker 51
See 
Pens for sale  to find these pens and more grouped by brand and style

The pens below are from Vacumania's 2008 December Update:

Holiday Parker "51" Insanity.

I suspect  that in the 30 or so years of existence of the organized hobby of collectable pendom (using the publication of Cliff Lawrence's first book for our starting point),  this update constitutes the largest single retail offering of Parker "51" fountain pens.  No auction, no catalogue, no website has had so many. Of course... i could be wrong ;)

Below take a gander at about 230 Parker "51" fountain pens.  A few have  sold or are on-hold from want lists, but most are up for grabs. A few will be available for shipping in January '09, as I found couple minor tweaks still to be done.


Included find:
  1. A gold Empire cap.
  2. Scarce red-band pens in three colors
  3. ALL the catalogued colors
  4. A few uncatalogued colors
  5. 49 double jewel pens (yes, 49)
  6. First Year pens
  7. A Mark-III Flighter
  8. 19 Plums
  9. Mint, boxed, stickered pens and sets.
  10. And, of course, much much more
Thanks to the pen restorers:

I collect pens. I have them restored by the pro restorers.  As fate and timing would have it, I was lucky to have a number of the pens below restored by Joel Hamilton, Ron Meloche and Danny Fudge.  Grand work as always.  But, I do owe a special note to Sean Gosse of Toronto, who on short notice and trying circumstances was able to get 60 or so of these up and running. And, finally,  this special offering could not have fallen in place without Ron Zorn's help. Friend, neighbor and well respected  restorer of old pens, Ron-- in order to accomodate a large portion of these pens,  which could have set his  usual queue back by a month--  let me drop by on multiple evenings so he could do overtime to get many of these done, while still providing timely  service to... everyone else.  If you happen to have pens needing repair, do give these guys a yell. You won't regret it.

Will I ever do this again?

Doubt it, at least not to this scale for "51" alone.   A fun but exhausting project.  After this, back to the usual 100-pen mixed updates.

Please be tolerant of typos:

Even if i priced the Empire at $25 by mistake, final call on prices is mine. No malice intended with prices, but errors happen. Thanks. Feel free to drop me a note with questions.

RED BAND "51" 1946-1947


Produced merely two years and released in small numbers, the "red band" Parker "51" pens from 1946-1947 are items of high cachet. Discontinued due to challenges repairing them, today they are quite scarce. Most commonly found as desk pens in black, pocket pens are more difficult to obtain, particularly in  colors other than black.

Clutch:  perfect clarity:    NA
Point: Fine Imprint:  none Size5 1/2" 13.9cm PRICE: $1400 
COMMENTS: Red-Band pens are high-cachet items in the "51" universe. Produced in limited numbers for couple years, they were tough to repair and- rumor has it- largely recalled.  A hoard came on the market about 8 years ago, further stimulating interest.  Most found are black desk pens. Pocket pens in general, and colors other than black in particular, are far harder to procure.  This one has  plastic red threads (also found in red metal) which, i'm told, is the more difficult to find of the two styles. This pen is very clean, including the lustraloy cap, which has a much earlier (and better)  "First Year" clip with horizontal feathers, large diamond and negative reverse imprint. Pen does not fill, is sold unrestored, and again- i'm told- makes for a difficult restoration.

The barrel assembly appears to be MINT with no ink expsoure. The cap clearly is not mint (fitted to the barrel after the fact, i'd imagine), and   has a much earlier (and better)  "First Year" clip with horizontal feathers, large diamond and negative reverse imprint. Pen has not been tested for filling and is a tricky repair, if restorable. May not be returned if you break it. Go figure ;)


Double Jewel Vac-Fill "51"
with SOLID GOLD Cap and TRIM


Near the high end of the cachet pyramid reside those "51" featuring solid gold caps.  Priced originally at $50 the pen,  these cost two weeks' gross pay for the average American worker during the 1940's, nearly a month's wages after taxes.
Given as gifts by those who had significant discretionary funds, these truly evinced Parker's, "Jewels of Pendom" philosophy.  Four cap patterns  originally were manufactured: Smooth, Empire, Fish Scale and Coronet, though some low run variants appear to exist, too.

COMMENTS: One of the keystone cacheities (neologism alert) in the "51" collecting sphere. Two tone solid gold cap. Solid gold trim. This one is the thin lip variant (also available with the more common wide lip, or so i'm told). No dings. Minimal use marks anywhere. Strong imprint, though not near mint razor yada yada. Fine Point.  Excellent color, noting one or two tiny specks in barrel where color is lighter. This is the only Empire I've ever owned.

 Vac-Fill "51" 1941
FIRST YEAR PENS
Double Jewel and Desk


Parker "51" was released for sale in the USA in 1941. The "First Year Pen"  is  believed to be  found with particular cap variants, to carry a clip  that features a larger-than-later blue diamond and to be stamped such that a peek at the reverse side of the clip shows a mirrored incuse "Parker", to  feature the metal "speedline" filler,  to have an early style clutch,  to have metal end "jewels", and  to show the manufacturer's imprint near the blind cap jewel rather than near the barrel's clutch ring.  While it is uncertain that all features persisted the entire year, or that all the first year features disappeared by the start of the 2nd year, pens that carry "First Year" features do have above average collector cachet.

COMMENTS: First year Blue Cedar pen with imprint by blind cap,  with metal bottom jewel, and with metal filling unit with diamond logo. Smooth Sterling cap (with proper imprint at top of cap) is an high cachet cap.  This one has later clip with small blue diamond, and has later (though perhaps still first year) clutch.  Clean pen with no dings, no longer with any rhodium plating, and with some wear to side opposite clip.

Cap has no dings and has good imprint at top. The "deco band" pattern at bottom shows wear at the bottom in a couple 4mm areas. As often found, no rhodium remains on the cap. It is at this point all silver.   The blind cap's imprint is complete with some obvious scratches scattered across the  imprint. . Clip has small nick in the ring at top. Tassie has slight edge brassing (i did place a cleaner tassie since this pen was shot pre restoration)

Point: F-M Imprint: Fine Size5 1/2" 13.9cm PRICE: $240 
COMMENTS:  Yeah, it is a first year pen with metal filling unit, imprinted blind cap and "Wedding Band" cap.  The clip is post first year, with small blue diamond. Both jewels are plastic. Blind cap imprint still shows most of "Parker" and "in USA 1", with "made", "51"  and part of "Parker" long gone. Blind cap imprint actually is better than shown in the pic as restoration done after the shot. Cap has been fully refrosted but still shows  a few dings, scratches and crimps onthe bottom third.  The barrel  has been personalized, "LOUIS SILVERSTEIN" in fairly shallow neat letters.  Entry level "First Year" no doubt with nice fine-medium smooth point.

There is a large oval mark on blind cap (visible in pic) that  appears to be a filled large deep scratch.  Imprint is full with overlying scratches. Cap has no dings and  withour brassing, but appears to have two sets of the 4-line clusters worn away (they are lightly stamped in this style). The tassie (blind cap ring) has some nicks and dings.    Entry level  First Year pen no doubt. Fine Point.

Double Jewel Vac-Fill "51"(1942-1948)
-Excluding solid-gold caps and first year variants-


Double Jewel "51" pens feature end screws ("jewels")  at both top and bottom of the pen. The blind cap is fitted with a gold-filled or gold tassie (trim ring), instead of being smooth, as for Single Jewel pens. Even excluding those pens with solid gold caps and those with "first year" features, the remaining Double Jewel pens are considered up-scale items from a collector standpoint, and do offer a wide variety of both colors and cap styles.  Some- even with gold-filled caps-  feature solid gold trim (clip and tassie) and this is known to be factory original.

Point: XF-F Imprint: Fine Size5 1/2" 13.9cm PRICE: $620
COMMENTS: Nassau is the most highly sought and scarce amongst the regular production colors from the vac-fill era. Cap is free of dings and of brassing. Blind cap tassie has edge brassing. Color is excellent. Imprint faint at top half strong on bottom half. The blind cap is a bit short relative to most "51" blind caps and (thus?) is bit narrow where it meets the barrel. Writes a very fine line.

COMMENTS: Yellowstone is one of the three high-cachet vac-era "51" colors. This one is a more than acceptable example. No dings and no brassing to cap/trim.  Good color including match between barrel and blind cap. Two tone clutch ring. Sharp imprint.  The blind cap's position is about a 99% match to barrel.

COMMENTS: Yellowstone is one of the three high-cachet vac-era "51" colors. This one is one of those "Would be excellent except for..." pens.  The trim is excellent. The imprint is excellent. No brassing and no dings.  Blind cap is perfect fit.  Buuuuut....  As is obvious the blind cap is  paler than the barrel (and NO, it is not a Buckskin blind cap. Sheesh!).  And - observable to skilled "51" players but readily overlooked by many casual users, the very tip of the gripping section (hood) has been a bit rounded, revealing an extra 1/2 mm or so of nib. Save $150 from pen sans issues.

COMMENTS: Buckskin is one of the three high-cachet Vac-Fill era colors. Until hitting this last-quarter 1948 pen, I hadn't realized Buckskin ran right to the end of the Vac-Fill Era. The feather (non-blue diamond) clip of course is correct for the last of the Vacs. Plastic is superb, with perfect color match amongst hood, barrel and blind cap.  Clean metal overall, noting (can see in the pic) high point brassing on the arrow and blind cap tassie.  Smooth writer, especially for such a fine point.

Probably one in fifty amongst what crops up at the pen shows. Clean barrel.  Plastic is nice with good color match of blind cap to barrel.  Complete bold imprint. There is some brassing only to the bottom tassie which has- no, i don't know why- a "first year style" metal jewel. Consider it a bonus. Down the pike you can swap it into a first year pen that has a pearl jewel in its blind cap. Note, this pen was shot PRIOR to restoration. Ya should see it now :)

COMMENTS: Bit of an entry level (regarding condition) pen. Clean cap. Nice imprint. Some color mismatch barrel to blind cap (I see many Cedar with blind cap lighter than barrel, indicating perhaps barrel darkening from ink or an unlikely number  of swapped blind caps), and the back end of barrel is a bit narrow. Blind jewel replaced (by me) with black jewel. Bottom of cap has one splotch (just <1cm) of brassing near cap lip Tassie has brassing and nicks. Entry level  Double Jewel pen.

Oddly, it has a metal bottom jewel usually seen on "first year" pens, though the blind cap color matches barrel perfectly. Front half of hood a bit lighter than back half. Smooth Fine Point. This one was shot pre restoration. The bit of tarnish (not brassing no worries) on the cap since has been wiped away.

COMMENTS:Clean cap and clip with  the (supposedly) earlier and scarcer  large diamond, negative reverse "parker" imprint.  Bottom ring (Tassie) is brassed and nicked;  clean findings otherwise.  Imprint ok save for "Parker" being faint.  Front half of the gripping section a bit lighter in color than back half.   Clean metal with bit of high point brassing on tassie only. In fact, I placed a cleaner tassie than what is showing in the pic (itself not bad) after this one was photographed.  Has early style (and more scarce) large diamond clip.  What sets this one apart is having one of the 3-4 smoothest nibs in this 200 pen update which has at baseline has  smooth nibs in most of the pens. Wish I could hand this pen to the various restorers next time I drop off 50 "51" pens and say, "Just make 'em all write like this".  Some pens are destined to be better writers than others.

COMMENTS: Clean pen overall. No dings or brassing to cap. "Typical" edge (1mm or so) brassing at main step of the tassie (ring) at bottom of blind cap. Nice color with bit of  slight darkening just the 1cm of the gripping section by the nib. Early cap with bottom pattern similar to seen on Parker Vacumatic Debutante. Clusters of 9 parallel lines above that. Single-border cartouche (area for engraving, unengraved in this case) appropriate to cap. First year variants  of this cap have double-border.   Nib is, what do they say, "One in one hundred"? Gives a nicely shaded stub-like experience even used by right handed writers (as am I).

Eye popping lined sterling cap. "Usual" high point brassing to tassie (bottom cap metal ring) edges.   Of interest, the Cordovan leans more toward red than the typical brown-leaning color. I'm still trying to figure if this is an era-specific finding or random batch variation (or differential fading, or...), but I have been leaning of late toward considering early pens to have this reddish cast and later pens more of the brown color.  The nib is killer.

COMMENTS: A true USER double jewel for one who wants the double jewel look without bells and whistles. The cap is nice. Well preserved rhodium. No dings, but the "usual" bunch of scattered nicks and score marks. The barrel has issues. The blind cap is a bit short though has fairly flush fit to barrel. There is no imprint left on the barrel.  A pen that has seen stronger days. But, no fatal flaws (depending on how ya define "fatal") and decent cap, which shows wear but no dings.   Smooth wet fine-medium point.


Demi  Vac-Fill "51"(1947-1948)

Demi (short model)  "51"  pens all are single jewel. Introduced in 1947, the Demi essentially is a one year model,  thus  markedly less common than either Demi Aerometric or the single jewel standard size pen. Unlike the Aerometric Demi- which is short and slender relative to the standard pen-  the Demi Vac-Fill is identical diameter to the standard size Vac-Fill. The cap for Demi is of different length (but again, same clutch) as the Standard, so often the  more scarce Demi is found with improperly  mixed parts, sporting standard size caps.  The Demi vac-fill pen can be considered a "stubby" pen, borrowing  a collector descriptor used for other pen series, indicating the pen is short but relatively fat.

COMMENTS: Demi is far less common in Vac-FIll form than in Aerometric. Indeed, Demi Vac Fill is far less common than standard Vac-FIll.  The Demi Vac-FIll "51" was introduced 1947, making it essentially a one year model, replaced in 1948 by Aerometric. Unlike the Aero, the Demi Vac-Fill is as chunky as the standard pen, making it something of a "stubby" pen to borrow collector convention from some other pen series.  The Demi cap often is found switched out for more common Standard cap. The Demi cap is shorter (though as fat) as the standard cap. All are found with the "transitional" look non blue diamond clip and wide-lip "PARKER" cap. This one has no dings and has had the cap finish completely refrosted. The barrel imprint is light.

COMMENTS: Demi Vac-FIll "51" pens are far less common than the small size Aerometric, as this model was introduced in 1947, rendering it essentially a one-year model, since the Aero pens appeared the next year.  The Demi Vac is more of a "stubby" model (borrowing nomenclature from other pen series) as- unlike the Demi Aero- it is as fat as a standard pen. Indeed, due to this and to relative scarcity of proper Demi Caps (they are shorter than standard caps) they often are found with standard caps as frankenpens.  Gold-Filled Demi caps are less common than Lustraloy. This one is crisp, with sharp imprint and no dings. Writes a medium line.


Single Jewel  Standard Vac-Fill "51"(1942-1948)

Single Jewel "51" is bread and butter to the user and collector of Parker "51". Well more common, overall,  than Double Jewel variants,  they offer relatively affordable pens in a plethora of varieties and feature the same solid manufacturing quality.   What often is less well known, is that some Single Jewel "51" pens actually are more scarce and valuable  than Double Jewel siblings. This is so mainly for the "tough" three colors, Buckskin Beige, Yellowstone Yellow, and Nassau Green, for which it has been asserted that  single jewel variants were manufactured only for export.

COMMENTS:  Ahhh, where to start?   I was sorting a bunch of pens and realized this one had an odd color. It is not the pale Dove Gray of the Vac-Fill era. Certainly it is not Navy Gray. It was a far darker color, i found myself calling, "Charcoal Gray".  Go Figure el  Zorno looks at it and says, "Gee, looks like Parker VS Color". Placed next to a Parker VS, the color indeed is very close. So, a "51" in VS Plastic?  Dunno. The VS has  a  more fragile plastic. This one feels like "51" plastic. So, a low run proto-color-ish thing done in the color of a VS but with "51" lucite?  Sill not sure.  I know I've never seen another. Indeed that "51" maven out in the midwest has only seen one other and that one, I'm told, is less clean.

I have not had this one restored, though wiping down the tarnish (the cap is NOT brassed ) will pose no problem.  I can ask Ron or one of the guys to restore it for you, if you'll take responsibility if it fails to survive unscathed. Restoration always poses a small risk.  Don't let the cap scare you- this is what they look like when they turn up in the wild ;)  No dings.

COMMENTS: Ahhh, where to start?   Vac-fill (1941-1948) gray pens are Dove Gray. Aerometric gray pens are Navy Gray, which has a warmer (hint of blue/green) hue.  However, quite occasionally turns up a Vac-Fill pen in the later Navy Gray.  I've spoken to a  couple fellow pen nuts who hunt "51" about as much as I do, and consensus (of an  admittedly limited sample) is that these are found without barrel manufacturer's imprint. And, indeed, this one lacks any imprint. Speculation exists that these were made in England, where it has been suggested vac-fill production continued a bit later than in the USA.  This is unproven, assuming the assumptions even are true.  Others debate whether this was a much earlier use of a color put on the back-burner until the Aero era.  I don't know.  One text considers it a pen done in prototype color.  "Prototype", though, is a word I find bandied too readily in our hobby.

This one packs a very clean USA-made GF cap  with parallel-lines pattern. Plunger is quite clear. Pen does fill, though I have not had it formally restored, as I'd hate to see any trauma happen to the pen. Nib is slightly off center.  I will be happy to have it restored for you for $25 surcharge, so long as it's your responsibility if the thing fails to survive restoration.  This is a legitimately rare "51" for someone who seeks a somewhat "advanced" pen.

COMMENTS: First-Year Parker 51's generally see maker's imprint at the end of the blind cap. Very late 1941 and very early 1942 pens have a single line imprint by the clutch, which gave way to the far more prevalent two-line imprint soon after.  This imprint actually is less common than the the typical First Year imprint. This one has clean imprint save that the "2" is barely visible.  The pen shows the early Cordovan color with more red in it than later pens.  The cap is free of significant dings, but has numerous light nicks and has no rhodium plating, though the warm silver looks nice.  Medium smooth point.   * The hood has a 1mm flaw at very tip (by nib) where a flake of plastic separated from the pen and was re-sealed.  You will need a loupe to see it.*

COMMENTS: For single jewel "51" with sterling cap, the condition of that  lined silver cap drives value. Most are heavily dinged with lost rhodium plating, etc.  This one is... not bad.  No dings. Partial  preservation of rhodium plating. Clean Cedar plastic. Smooth fine point with nice ink flow.  The negative is that the undinged silver cap has lots of micro scratches, pin marks, some wear, though without loss of the plating (save at very bottom).  A well used, not abused, still well plated cap.

This is a kosher mix. This one is... ok.  Writes nicely. No actual dings, but scattered  tiny nicks and micro scratches. You can see some light brassing to the clip and there are a couple 3mm spots of brassing at bottom of cap.

COMMENTS: Blue Diamond disappeared a few months before the Vac-Fill  era ended.  This 1948 pen is correctly found with the long arrow clip. The wide-lip cap is the less common of the two 1948+ "early Aero era" caps.  Couple light marks on cap, no dings.  Blind cap alignment about 99%. Couple specks of brassing to clp ring next to clip. Iridium looks broad to my eye, but the line put down by the pen is medium.


Aerometric Mark I-III "51" (1948- 1970 or so)

With the exception of the all-metal Signet, Flighter and Presidential models, the plain old "Aero" long has run  second fiddle to the Vac-fill era pens. Fewer cap varieties are found. All pens are single jewel. Overall, the pens are more common.

But, with a surge in interest in pens by  folks who just want to use their pens, the Aero has come into its own. While most- contrary to myth- do need some degree of restoration when found in the wild, the Aerometric pens  are more likely at least still to fill and write  than are most other vintage self-filling pens. The one-squeeze filling action also is popular with writers.   Growing collector appreciation for the color hierarchy has added fuel to the charm of collecting this generation of Parker "51".  The series persisted more than 20 years as Aerometric, even in the face of new high end models appearing from Parker. The final forms of the pen, Mark II and Mark III, at first glance appear more like some of those other pens than they do "51" proper.

COMMENTS: Interesting and lovely Signet set.   Some cite 1949 for the introduction of this pen. And, that might be so, depending on some of hte nuances of "introduction". Still, the pen in this set packs a late 1948 date code.  The barrel has cartouche (unengraved) for optional personalization. I believe later Signets lost that feature. As is expected for early Aerometric pens, it has a long clip, barrel imprint and chrome "press 6 times" filling unit.   All imprints very sharp. Clean set. Functioning Pencil.

Nib looks to be Octanium  The thread sleeve inside the metal barrel was loose when I acquired the pen. Ron Zorn graciously sealed it back in place.

COMMENTS:Where or where to start with this one.  Mark III pens (at least in the USA) were manufactured just three years around 1970... the last of the "51" pens, matey.  This is the first Flighter Mark III I've ever seen. It is marked "Parker 51 MK III" on cap and on filling unit.  This one was manufactured in Brazil (or... for Brazil).  This is the  first Parker "51" I've ever seen with Brazilian markings.  So many firsts.  Oh yeah, did I mention it has a Mark III Flighter BALLPOINT, too?   Whilst I'd venture guess that others have at least played with "51" Flighter BP's, this is the first of any Mark I've handled, never mind Mark III and never mind from Brazil.   Very clean pen set.  Barrel of pen alone is personalized as per above. Neat item.

COMMENTS: Plum is the high cachet Aerometric color. This is, amongst the 30 or so I've offered online the last couple years, the only full size pen with gold-filled cap. It's 1948 date code makes it a "first year" Aerometric, not that anyone really cares.  This one has proper early long clip. Has the early "press six times" filling unit.  Nib looks broad and writes on the cusp of full broad (on the Medium edge of Broad). Great writer.

COMMENTS: A proper Special with Octanium nib, black top jewel and- in this case- reflective non-frosted Special cap.   Despite the Demi status, not a tiny pen, as long as the prior Parker Vacumatic Major and bit thinner. Specials are relatively uncommon in Forest Green.  Hearsay babbles something along lines of Forest was fading from production as Special was introduced, but I hardly insist. Superb condition, especially given the unforgiving reflective cap (Special alone sees this cap style).  Double Sticker (other side cites the "electropolished" point.   Medium Point.


Aerometric "51"
Midnight Blue


What passes for my experience suggests the prevalence of Midnight Blue is more on the order of Forest Green than of the more common colors to follow. Some of the variation in color seen below really is just due to camera's white balance attempt, but  like many Aero colors, batch (or era) variation seems to be in play, too.

COMMENTS:Whilst Midnight Blue commonly  is not lumped with the high-cachet colors Plum, Forest Green and Cocoa, in my handling an ever increasing quantity of 51's, that Midnite is well less common than I expected.  The cap is later style with clutch fingers, matte appearance, Parker logo and "51" marked.  Whether intended for company use or to be sold to airline aficianados, I cannot say, but this is the first "51" I've owned with an airline logo on it.  The pen grades full mint. Fills well with water test. I cannot comment on ink-flow adjustment. May not be returned if inked or dipped.

COMMENTS: Whilst Midnight Blue commonly  is not lumped with the high-cachet colors Plum, Forest Green and Cocoa, in my handling an ever increasing quantity of 51's, that Midnite is well less common than I expected.  Lustraloy cap has moderate original frost and no dings.  Sweet Medium Point. PLEASE NOTE:  I originally gave this pen to one of my favorite restorers to serve as a (nice) parts donor, because it had a bold honkin'  heat stamped personalization in the barrel. Figured the rest of pen would better serve other 51's in need, as the  stamped name was just... too much.  So... this restorer  gets this evil gleam and his eye after looking at the pen and runs off to the other room, leaving me with Oreos and iced tea.  Half hour later, the pen comes out of the restoration room with no imprint. I know how it's done, but still I was impressed. No sign left on the barrel but perhaps a hint of light reflex shift in one tiny area. Smooth to the touch. I believe you won't be able to tell it apart from the usual $180-ish pens, but I like full disclosure.  Great writer.  BTW- yeah, El Zorno did it.

COMMENTS: Clean Teal pen. The cap probably dates a bit before the rest of pen, as the Teal assembly has no barrel imprint and has the "press 4 times" brushed finish filler with black end piece. Of the two early Lustraloy caps, the wide-lip cap is less common and more impressive looking. The cap has the  early style long clip as well.  Cap might be slightly earlier than rest of pen, but a "better" Cap. Nice preservation of original frost.

COMMENTS: The Special was the "affordable" Parker "51" with it's 1950's introduction. This one is proper with black top jewel, "special" filler and Octanium nib. Lack of barrel imprint is correct on post 1952 pen. Very clean plastic. No Dings. Moderate original frost.  Halo logo on pen dates it, i suspect, to after 1957. Very smooth fine point... a nice writer. Pencil works well and has complete eraser. Of note, the pencil does have a "parker" barrel imprint, so might be earlier issue than pen.

Pen writes nicely.  Pencil is the less-common Liquid Lead variety, in NM condition and does put some line on paper- most of these are long dried. Still, cartridges for these are hard to find in working shape, so long term this neat pencil will serve mostly as a collectable. The pencil still has frosty lustraloy finish. The pen has a shiny finish to cap.

The breather hole in barrel side dates pen to 1960 or later.  The pen is strictly mint. Never met ink.  Superb condition. May not be returned if inked or dipped.

COMMENTS: Possible mild mix. The cap is the "better" first style Lustraloy cap seen from 1948 to ??? Filler imprint suggests early 1950's (perhaps overlapping the cap). The barrel has no imprint (that having gone bye bye around 1952), so cap perhaps is bit early relative to the pen.  Given the swappage that goes on with ubiquitious Aero parts, this is a borderline issue. Cap has superb frost, but does have one tiny (teeny!) pock about 90 degrees to left of clip.  Very smooth medium point. Nice eye appeal.

The filler is not marked "made in USA"- consistent with the English production and the font is different from the lettering on USA made pens.  The wide cap lip has "PARKER" in larger letters than my USA-made caps lying about, but I'm bit more vague as to the cap variations on overseas "51" pens.  Cap has nice preservation of frost. Filler unit is clean.   Barrel has some wear with faint imprint.  Broad+ wet writing nib, making for an outrageous writing experience :)

COMMENTS:Where or where to start with this one.  Mark III pens (at least in the USA) were manufactured just three years around 1970... the last of the "51" pens, matey.  This is the first Flighter Mark III I've ever seen. It is marked "Parker 51 MK III" on cap and on filling unit.  This one was manufactured in Brazil (or... for Brazil).  This is the  first Parker "51" I've ever seen with Brazilian markings.  So many firsts.  Oh yeah, did I mention it has a Mark III Flighter BALLPOINT, too?   Whilst I'd venture guess that others have at least played with "51" Flighter BP's, this is the first of any Mark I've handled, never mind Mark III and never mind from Brazil.   Very clean pen set.  Barrel of pen alone is personalized as per above. Neat item.

COMMENTS: The Mark III "51", final form for this venerable series, was produced for about three years around 1970 (yes... 1970), thirty years after the "51" appeared in the USA.  Taking contour cues from the Parker 61, this late "51" differentiates from the Mark III by presence of metal top jewel and more coarse barrel threads.  This one is mint with original price/nib-grade tag.  Water testing shows a wisp of ink so pen has been dipped. At the pen shows we debate whether "Mint Dipped" is fair grade or if any ink (these were tested pre-sale after all) means "near" mint. Of course, given what I see advertised all over the web as "near mint", this one is something of a cut above. Ahhh... philosophy. Anyway, may not be returned if inked.
