PLANET TANK - MASUDAYA - JAPAN
Judging by the number that have survived this was a popular space toy. It is a dark blue lithographed tin battery operated non fall tank with green dome and large rotating plastic antenna. Also produced with a blue dome. The tank is most impressive when switched on: bump and go non-fall action with a rotating antenna and a light show inside the dome.
There are two know versions:
1 Marked "Planet Tank" on the side (Top)
2 A less common one (Bottom) marked "Space Patrol".
Both appear to have been released in the same Planet Tank box. The domes can be blue or green
