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.

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.
