Pen Profile:
Parker 51
16159: Parker 51: first-year in grey, Lustraloy cap with inlaid gold filled band, long clutch, Blue Diamond clip, two-tone clutch ring, aluminum end jewels and Speedline filler plunger with diamond mark on end. Good clean imprint by blind cap tassie with 2nd quarter date code. Typical stress marks at end of barrel from past overtightening of filler unit, do not affect function (see details). A nice clean entirely original example fresh to the market.
DATE: 1941 • CONDITION: fine-exc* • NIB: medium • $495
11302: Parker 51: Cedar Blue first-year, smooth sterling silver cap with imprint at top, metal jewels appear to be silver rather than aluminum; good blind cap imprint with 2nd quarter date code, aluminum Speedline filler with diamond at end of plunger. Neatly cut oval depression on hood behind and in line with the nib appears to be an early form of nib position indicator, as later adopted for the 61, but whether factory or aftermarket cannot be determined. Name on barrel, a few pinhead dings to the cap, slight hood shrinkage.
DATE: 1941 • CONDITION: fine • NIB: fine • $785
15525: Parker 51 set in box: scarce and unusual early wartime pen, black single-jewel with early first-year style 1/10 14K gold filled cap with imprint at top, alternating pairs of straight and squiggly lines, good barrel imprint with 4th quarter date code. Matching pencil uses .9 mm lead, both caps are clean and crisp, noting monograms lightly engraved on rims. Overall excellent condition but for typical shaving of the barrel to blind cap joint.
DATE: 1942 • CONDITION: fine-exc • NIB: medium • $595
15925: Parker 51: dark blue Vac-filler, scarce coin silver cap with grouped parallel lines pattern, rhodium plating, gold filled over silver wartime Blue Diamond clip; filler unit with diamond imprint on plunger end. Strong barrel imprint with 3rd quarter date code. Parker's 1942 production levels were low as they were concentrating on producing war materiel.
DATE: 1942 • CONDITION: fine-exc • NIB: medium fine • $325

Pencil is in much better condition than the pen, excellent but for one small ding to the nose cone, pen has been used much more, scattered nicks and bumps to the cap, still in good working condition.
