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 three pieces. This is one of three versions that were produced by Keystone. It was produced after 1942. The box is labeled #657. At this point I do not know when the #206 became #657 or if there was a period that say both numbers being produced.
From my private collection.
Did Keystone make smaller Navy ships? I have one about 5′ long that is number 251.
Hello Hugh,
Tillicum made small wooden ships that size. As I recall one was labelled the 251.
