Sterling Silver caps with gold filled clips, lined pattern with chevron band. These caps all had a rhodium plating to prevent tarnish. The finish did not stand up to wear too well, wearing inconsistantly, leaving a very unattractive appearance. In addition, the soft metal is very prone to dents and dings, and finding caps in perfect condition is very hard. These caps are the most often advertised version of the vacumatic “51s” found in print ads. Common Caps

Lustraloy (stainless steel) caps with “Jeweler’s” band and gold filled clips. These caps had a matte finish with a shiny raised 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. These caps were also available with nickel plated clips.

Coin Silver caps with rhodium plating and gold filled clips. Line pattern of seven lines, space, one line, space, and then seven lines ( IIIIIII I IIIIIII ) repeating all around the caps, and plain cap bands. These caps are not marked as to silver content (.900). The plating did not hold up to wear well, and wears unevenly. Soft metal dents easily. Very hard to find clean caps with original finish and no marring to plating. Common Caps
