Circa 1962, Made in Japan by Daiya - The Space Conqueror. Takes two D size batteries in the oxygen tanks on the back, walks along, stops then raises its gun which makes machine gun noise with flashing light. It normally has a rotating radar dish rotating on the top of dome but as with mine here, is often missing, repro required. Also comes in red probably the first version known as Cragstan X-70, and a rarer version in green. A very nice 1960s space toy with great tinplate lithograph.
