This is a set of naval miniature game rules for WWI and WWII ship battles, popular during the 1940's. From the Introduction: [A] game that can be played by almost anyone not too heavily upholstered to bend over and maneuver a model ship across the floor. It is also, fortunately, a game whose practical details can be learned in 15 minutes or less, in spite of the apparent complexity of the rules. Having been told how to maneuver his ship by the speed-scale and how to lay the firing arrows, the rest is up to the individual's keenness of eye and his ability to keep cool amid excitements.
