GEAR ROBOT, STOPPER AND NO STOPPER VERSIONS - HORIKAWA - JAPAN

VISIBLE GEAR MECHANISM Small grey tin wind up robot with visible gear mechanism. This is a development of the small boxy robot design with a greater gear complexity in the chest. Circa 1964.

There are two Versions:
Stopper Version (top): this version has a "stopper" switch on the back. The stopper seems to be associated with the red eye version. It is probable that this is earlier than the no-stopper version based on the tendency for later runs of toys to be simpler than early runs.

No Stopper Version (bottom left)
The Japanese box version (bottom right) has plastic legs, an indication that it is a later version with no stopper.

The robot retains the clear red dome of the earlier two gear sparking version, but the spark action is now confined to the chest.
