This model is the AHI Oldsmobile (1959) in blue.
The model has a one-piece metal body, 46mm in length. It has been molded with the body casting having representations of the grille, lights, and front bumper cast at the front, doors and door handles to the sides, and rear bumper to the rear. The base is a solid, shaped, recycled tinplate item. There is no glazing. The original wheels are black plastic and attached to steel axles with a large slightly domed 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" and country of origin "JAPAN" stamped in to the tin base. It is held in place by two machined rivets.
I do not know exactly when this item was issued but it would have been between 1959 and the mid 1960s.
