ELECTRIC REMOTE CONTROL ROBOT, VERSION B - MASUDAYA - JAPAN
R-35. This rarer variation has a red plastic remote control. In addition the box is squarer and carries the Masudaya MT logo.
There is some debate about the existence of a detachable remote control. Photos exist of a version with a two pin adapter that fits into the robot body. It is considered that this is probably a post-production adaptation by a collector.
VERSION B: Masudaya smaller box. Plastic battery operated remote. Slightly darker blue litho.
