BUCK ROGERS XZ-31 ROCKET PISTOL - DAISY MFG - USA

This is the first ever toy space gun. The gun is manufactured from heavy gauge blued steel, a fact that explains why so many have survived. The gun has Art Deco styling with a flared barrel tip and distinctive two-ring structure on the top. Pop gun action. Available in plain steel and blued steel versions, though the latter usually loses its finish. Released for Christmas 1934 and certainly on sale as early as July. The gun was a very popular item and stores soon ran out of stock. 9.5" long.

The gun was designed to produce a loud report without firing a cork.

The patent for this gun was granted in July 1935.
