Vintage Sink The Ship Board Game circa 1940

Game Good Condition All Pieces Present Box Good Condition 

Vintage Game From The Estate of An Avid Game Collector

Shooting game. 6 targets, made of card. The targets are 'stood up' in wooden supports. A nice cannon is used to shoot at the targets. A player must knock over a ship to count as a 'success' and earn a point. You can decide before you start the winning conditions, first to score 5 successes wins, that sort of thing.
Box - "A battling good game".
I'm guessing the date but it looks to me like a WWII vintage game circa 1940, when children, particularly boys, were very interested in all things military.
