10168: Parker 51 Club button: large metal pin back, 3.55 cm in diameter, given to Parker dealers as part of a sales contest promoting the initial release of the Parker 51; rare, and probably even less commonly seen than the sought-after contest award pens.
10867: Parker 51: black Vac-filler, wartime production with 1/10 16K gold filled over silver cap in grouped parallel lines pattern, Blue Diamond clip is also gold filled over silver; two-tone clutch ring, sharp barrel imprint with 2nd quarter date code, characteristic wartime filler with celluloid body, plunger with diamond emblem on end.
10189: Parker 51 nib extractor: original factory-issued repairman's tool, ring 2.5 cm across, curved steel blade with stud on top is inserted between nib and feed, stud snaps into hole in nib, allowing nib to be pulled out without removal of shell (hood). Slightly shortened at tip (the thin steel easily chipped), still functional but use not recommended nowadays due to risk of damaging shell.
10860: Parker 51: unusual Canadian-made grey Vac-filler, fully marked, characteristic Blue Diamond clip with high placement of the Diamond, cap material is odd and appears to be rhodium plating over brass or cupronickel; no date code visible on barrel, but Canadian nib bears 1947 date.
10866: Parker 51: burgundy Vac-filler, 1/10 14K gold filled cap with fine parallel lines pattern, plain arrow clip; older style semitransparent hood, barrel imprint is crisp with sharp "T7" date code, 2nd quarter; nice clean pen, no brassing to cap but one pinhead mark to back.
10865: Parker 51: grey Vac-filler, sterling silver cap with geometric band, fine parallel lines pattern, gold filled over silver Blue Diamond clip; clean barrel imprint with 1st quarter date code, postwar production using wartime parts. Cap has a clip mark and usual blotchiness from partial loss of original rhodium plating, but no dings and little wear.
10861: Parker 51 Demi: dark blue Vac-filler, 1/8 14K gold filled cap in fine parallel lines pattern, 12.2 cm long, bold crisp barrel imprint with 4th quarter date code; Vac-filling Demis were produced for a short time and are relatively uncommon, and are shorter and thicker than the later Aerometric filling Demis.
10110: Parker 51 demonstrator: transparent Lucite Vac-filler, clean Lustraloy cap, chrome plated trim, sharp barrel imprint with 3rd quarter date code; clean example, noting one stress mark on the shell, and smaller stress lines around barrel monogram (see details). These pens were not sold to the public, made for a brief period in 1947-48 for dealers, salesmen, and repairmen only.
10667: Parker 51: grey Vac-filler, uncommon coin silver cap with grouped parallel lines pattern, gold filled over silver Blue Diamond clip, barrel imprint with 4th quarter date code, some blotchiness to cap from usual wear to rhodium plating.

10862: Parker 51: Aerometric filler in Cocoa, 1/10 12K gold filled cap; a smooth writer, sac has been replaced, cap has shallow dings and marks, Y-shaped impact crack at end of barrel (see details). A sound and attractive user.
