DIAMOND PLANET PROTOTYPE - YONEZAWA - JAPAN

This is the prototype of a battery operated Diamond Planet Robot in plain metallic blue color. It has a brown tag on the bottom that reads: "37-11-7" as the manufacturing date. This is the Japanese Emperor dating system that equates to 7 November 1962.

It is not clear if this toy was designed before or after the windup version. The body shape, head and ears are the same as on the wind up Diamond Planet but the window and battery box are different.

It has always been speculated that the shape of the Diamond Planet was designed to accommodate batteries, and this seems to confirm this.
