This model is the AHI Mercedes Benz 300SL (1950s) in grey.
The model has a one-piece metal body, 47mm in length. It has been molded with the body casting having representations of the bonnet, lights, grille, and front bumper cast at the front, side trim to the sides, and rear bumper and boot lid 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 base plate.
The base plate no manufacturer's mark, but the country of origin "JAPAN" is 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.
