This set has a ship that measures 13.5″ x 3.25″ and a submarine that is 8.5″ x 2.5″. The ship has a mousetrap spring in the center that will explode the upper deck from the hull when the red target is struck. The deck would explode into seven pieces. This particular design is the first of three versions. It was produced from the late 1930’s until 1942.
