PISTON ROBOT, JAPANESE BOX - YONEZAWA - JAPAN
Blue plastic battery op piston robot. Yellow arms. Red plastic visor face. Visible engine pistons in chest. Made by Metalhouse in Japan. Takes two c-cell batteries. Same mold as the Yonezawa Talking Missile robot. Possibly appeared in a late 70's FAO Schwarz catalog.
The influence of Metal House is evident in the SH styling of this robot.
