WASSERSPRITZPISTOLE SPACE WATER PISTOL - GEOBRA - W GERMANY
A transparent plastic space water pistol. This gun is based on the Rex Mars Planet Patrol by Marx. It also has features seen on the Mars water gun by Mak's, H.K. The gun has a classic shape with with rings on the barrel, fins on the muzzle and lines on the body. A streamlined telescopic sight is mounted at the back. The gun has a small working compass on one side of the handle and is marked Geobra on the other side. Sold carded (picture, anyone).
Note the square trigger guard, the larger sight and the compass, all of which distinguish it from the earlier Marx version which has a rounded trigger guard, smaller sight and no compass.
This gun features in the Geobra 1957 catalog. It was also on sale as late as 1963-4 in the Hullinghorts Spielzeug catalog.
