This model is the AHI Dodge Military Horse Box Truck in olive with tan horse box.
The model has a three-piece metal body, 49mm in length. It has been molded with the cab and chassis casting having representations of the grille, lights, front bumper and doors cast at the front, fuel tanks and rear wheel guards to the rear. The base is a solid, shaped, tinplate item, the rear horse box is cast metal (copied from Matchbox by the look of the design). There is no glazing. The original wheels are grey plastic and attached to steel axles with a large flat head on one side and crimped ends on the other. They are held to the chassis by means of the baseplate.
The baseplate has the manufacturer's mark "AHI Brand Toy" in a rectangle with the country of origin "Japan" marked just below it. It is held in place by two machined rivets.
The item comes in the distinctive small acrylic display case associated with this series of toys — clear acrylic upper with black plastic plinth. The underside of the plinth is simply marked "JAPAN". The clear acrylic upper carries a pinkish price stamp of 29c.
I do not know exactly when this item was issued but it would have been between 1950 and the early 1960s.
