This is a hand held dexterity puzzle that measures 3.5″ by 5″. It is cardboard with a clip around metal frame. The bomber “floats” in the frame. The object is to get the wooden “bombs” into the bomb bays on the back of the wings. Difficult and entertaining. Date and manufacturer unknown. Assumed to be from early WWII before the ban on metal for toys.
From my private collection.
