Although the Japanese are best known for their toy ray guns made of tin, they also produced a number of all plastic guns, including the Rocket Gun. This is a clear, blue plastic squirt gun with an ingenious plunger mechanism at the rear of the gun which is used to draw water into the toy. After the water chamber is filled, each time the trigger is pulled the plunger is then pushed forward, expelling the water from the guns water chamber. Length 6 inches.
