Gold filled Cap with unusual line pattern that does not go the whole lenght of the pen. Found on a red band demonstrator dated 1946. Probably a model shop prototype cap.

Very Rare Cap

Parker

Lustraloy (stainless steel) caps with chrome plated clips. These caps had a matte finish with a shiny cap band when new. Finish was more "brushed" than the later aerometric series caps. The finish did not stand up to wear too well and quickly wore off. This was a transition cap after the Blue Diamond guarantee was discontinued. Usually found in vacumatic "51" pens dated 1947-1948 and the early aerometric series pens of 1948-1949.

Common Cap

Gold Filled Cap with gold filled clip, with pattern of closely spaced lines all around. Note the "Parker" on the band, unlike the earlier Blue Diamond caps. Found on 1947 to 1948 Parker "51" vacumatic filler pens, single and double jewels.

Common Cap

A previously unknown Solid Gold 14k cap with a smooth/no pattern finish and 14k clip. Before this cap was found, the smooth 14k solid gold caps had only been seen with the blue diamond clip. This cap has the plain arrow clip and "Parker" on the cap, which would make it correct. In addition, it has the normal tab under the clip, found in all plain arrow caps.
