10236: Parker Golden Arrow (?): very early red pearl laminate lockdown-filler, 12.2 cm long, gold filled trim, two cap bands, one-piece section-barrel construction, two-tone nib with single central rib on arrow; rare barrel imprint with no mention of model name, no date code. Only a handful of these pens are known, and it seems most likely that they either predate the original Golden Arrow or immediately postdate it, prior to its renaming as the Vacuum Filler (discussion here). Condition is mixed, with hardly any wear and crisp imprints, but with a couple of cap lip cracks and a partial circumferential hairline under the clip where two laminations appear to have separated due to age shrinkage over the inner cap (see details). Notable super-broad factory italic nib, name engraved on barrel. Sac has been removed to preserve color.
10138: Parker Vacumatic: early demonstrator-like "Crystal" model, black with transparent barrel, 12.2 cm long, gold filled trim, strong barrel imprint, pre-date code, nib is slightly later with 1937 date code; early chrome-plated lockdown filler fully functional, noting dent in plunger and pitting.
5960: Parker Vacuum Filler: black with fully transparent barrel, 12 cm long, gold filled trim, no brassing, good imprint (usually weak), typical even barrel darkening, "VACUUM FILLER" imprinted nib.
10212: Parker Vacumatic set: early top-line full-sized lockdown-filler in black, 12.8 cm long, gold filled trim, good barrel transparency, imprint with early date code, 4th quarter; matching pencil is slightly later, with 3rd quarter 1936 date code. Set is well used but sound, pen nib is a later replacement, subtle surface rippling to pen barrel due to differential age shrinkage of laminations. Pencil uses 1.1 mm lead.
10240: Parker Diamond Medal "Vac-Fil" Vacumatic: uncommon burgundy pearl and black marbled pump-filler, 11.4 cm long, gold filled trim, barrel transparency excellent, lockdown filler, Diamond Medal nib is smooth and soft, but not the usual type found on this model. Step at blind cap joint, name on barrel, cap lip cracks have been sealed and reinforced by a black celluloid internal sleeve. This model was made by Parker for retail by Sears, Roebuck & Co.
10214: Parker Vacumatic set: red pearl laminate lockdown-filler, 13 cm long, gold filled trim, excellent barrel transparency, imprint with 2nd quarter date code, striped jewels and section, early-style skewed striation pattern on cap, barrel laminations slightly skewed as well (indicating parts turned from solid rod stock, rather than later process of wrapping tubes from sheet). Two-tone nib is slightly later, with 1940 date code, nickel plating largely gone from filler plunger. Matching pencil has 1st quarter date code, uses 1.1 mm lead, but lead is propelled only, does not retract automatically.
10191: Parker Vacumatic set: uncommon golden pearl laminate lockdown-filler, 13 cm long, gold filled trim, striped section and jewels, two-tone nib with excellent plating, excellent barrel transparency, strong imprint with 4th quarter date code, matching 1.1 mm pencil has 1st quarter date code. While this color is relatively common in later Vacumatics, it was introduced only at the very end of production of the original lockdown series. Pen is extremely clean, noting slight shrinkage of cap at very top right below the clip.
7717: Parker Vacumatic: golden pearl laminate double-jewel, 12.8 cm long, gold filled trim, striped pointy jewels and section, lockdown filler, good barrel imprint with 2nd quarter date code, good barrel transparency, nib is a later replacement, with date code for 1946; the color is common on later Vacs, but is hard to find on earlier models, having been introduced only at the tail end of the lockdown filler era.
10201: Parker Vacumatic: golden pearl laminate, 12.8 cm long, gold filled trim, striped jewels and section, excellent barrel transparency, strong barrel imprint with 3rd quarter date code, trim plating excellent, but plating gone from two-tone nib and there is a light longitudinal scratch just under the barrel imprint; this color was introduced only at the very end of lockdown-filler production, and examples are relatively uncommon.
5580: Parker Vacumatic Junior: small grey pearl marbled, 12 cm long, chrome plated trim, outstanding barrel transparency, roughness to cap band plating, bold imprint with 4th quarter date code, lockdown filler, 1946 date code on Arrow nib.
10708: Parker Vacumatic: golden pearl laminate full-size Deluxe, 12.9 cm long, double-jewel, lockdown filler, striped jewels and section, good imprint with 3rd quarter date code, two-tone nib with 1st quarter code; scarce color for this model, added to line late; exc transparency, usual even plating wear on nib.
9779: Parker Vacumatic Junior: black "Shadow Wave", 12.3 cm long, gold filled trim, lockdown filler; diaphragm has been removed to preserve near-perfect barrel transparency (pen will not fill); crisp imprint with 1st quarter 1938 date code, nib has compatible 4th quarter 1937 code, overall condition is as new, probably never filled.
10981: Parker Vacumatic: black laminate, 12.8 cm long, wartime gold filled over silver trim, Blue Diamond clip, uncommon "jeweler's" cap band with fine parallel lines pattern; barrel imprint with 3rd quarter date code, filler plunger with diamond mark on end, Junior-sized nib as is usual with this configuration.
9153: Parker Vacumatic Sub-Debutante: unusual green pearl laminate, 11.9 cm long, nonstandard chrome plated trim, barrel imprint worn but partially legible, fine barrel transparency. Green Vacs normally came with gold filled trim.
10137: Parker Vacumatic: uncommon black Canadian model, 13.3 cm long, gold filled trim, like a long Major, but with non-Blue-Diamond clip of typically Canadian form. Good imprint with large date code, fine barrel transparency, very fine nib has slightly later (or earlier?) date code, good for writers with a light touch.
