Parker "51" Vacumatic Series Plain Arrow Clips 1947-1948

Lustroloy (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

Gold Filled Cap with gold filled clip, with pattern of lines in groups of 3 all around the cap.  This is the same unique pattern later used on the all gold filled aerometric Signet.  These caps were found a 1947 dated double jewel barrel.  Note the vacumatic rotary pencil, which would make it impossible to use a later cap from a "clicker" Signet pencil.   Uncommon Cap

Gold Filled caps with gold filled clips.  Line pattern of group of five lines tapering up to one point near the clip, repeating all around the cap, and cap band with "Parker".  Gold filled content at bottom of cap.  These caps have deep engraved lines unlike the later aerometric series tapered line caps.     Common Cap
