RADICAL ROBOT - YOSHIYA/NGS - JAPAN
Metallic blue tin battery operated skirted robot with bump and go action. This is basically the metallic blue version of the Chief Robot Man in a different box.
Without the evidence of the box it is be impossible to say whether a particular robot started life as a Chief Robot Man or a Radical Robot. The box art is appreciably different. The box carries the Cragstan logo and the NGS logo.
The color is usually metallic blue but silver grey versions have found their way into Radical boxes, either at the factory or later. The arms are always metal.
Circa 1962.
