Mattel ©1966 Space Productions. Gun consists of two main hard plastic pieces which can be assembled into larger rifle or used as stand-alone weapons. Gun has red viewing scope, whistle attachment and launches "Roto-Missiles," (saucers). Originally came with
3 saucers. Assembled size with both gun units in place is 20" long. Larger of two units has foil sticker with Mattel logo and
"Lost in Space / Roto-Jet Gun" on one side of barrel while opposite side has detailed simulated controls. This unit produces a
loud pop when trigger is pulled and known as the "pistol" while the smaller gun is the "Roto-Launcher." When the smaller unit is connected to the front of the larger unit, it forms a sub-carbine and when reversed, forms rifle. Slightest traces of wear.
