MR PATROL, ROBOT VERSION - HORIKAWA - JAPAN

A large black tinplate robot "With siren". The brightly lithographed chest plate has a clear red plastic panel above. The chest is designed like a meter with gauges on either side. The robot walks with lights and siren sound. The dome does not light. Red plastic feet. The robot advances, stops, raises his arms and makes a siren noise. The head structure is the familiar Horikawa boxy design with chrome ears and a cylindrical yellow plastic dome.

At the fast end of the motor, the top, there is a sort of fanblade made of white nylon. This is surrounded by a cage with slots with the appropriate distance. This forms the siren. An intermittent gear arrangement makes a lid move over the top of the siren so changing its pitch.

English and Japanese boxes shown.

There is an astronaut version of this robot that appears in the 1968 Lewis Galoob Toy Catalog. The robot version date is probably similar.
