LOST IN SPACE ROTO-JET GUN - MATTELL - USA
This large silver plastic modular space gun consists of two main hard plastic pieces which can be assembled into a larger rifle or used as stand-alone weapons. The gun has a telescopic sight, a whistle attachment and shoots two Roto-Missiles spinner saucers. The gun produces a loud pop when the trigger is pulled. When the smaller unit is connected to the front of the larger unit, it forms a sub-carbine and when reversed, forms a rifle. The box indicates four configurations.
The gun was also sold in a plain mail-away box by Sears. There is also an unlicensed Japanese version which does not reference Lost in Space. (CMDDD)
