R-1 Robot Gray. Large 12" tall all tin skirted battery operated Gray R1 Robot with bump 'n go action, flashing eyes and dome. Styled in the image of the classic 1950's "Gang of Five" robots and now getting hard to find. R1 was produced in many styles by Rocket USA, but they are now discontinued and sold out, so this may be your last chance to buy this very cool robot toy.
