The Atomic Disintegrator Cap Gun was made in the early 1950s by Hubley Manufacturing Co. who primarily produced many cast iron toys. This the only ray gun produced by Hubley is the 2nd one I own, but it is still central to my collection. This unit has restored handles, courtesy of my Dad (a antique restoration expert). It was either not manufactured with Zinc coating or it has worn off over the years. From reading about this subject I believe there were two versions, zinced and metal. Length 8". c1950s
