"1930's USA Daisy CO's Rare Buck Rogers No. U-235 Atomic Pistol with Original Box- Arguably the best looking Art Deco style ray gun ever produced. The Atomic Pistol, or U-235, was made around 1935. Produced in a copper and a blued finish, the gun was manufactured by Daisy. This gun was sold in stores as well as merchandised as a Cream of Wheat premium in 1935 and a Popsicle premium in 1939. Length 10 inches. Copper is by far the rarer finish."
