Naval combat dexterity game was published in 1940. Two plastic and metal ships are involved with the battle. A submarine fires an aluminum torpedo at a battleship. If the torpedo strikes the proper target zone on the battleship the vessel "explodes" and falls apart... the game mechanic is similar to the 1980s Milton Bradley classic Torpedo Run. Includes the ships, the torpedo, and the rules. More experienced captains can take longer shots or otherwise embellish the game, but the concept was quite simple.
