1940s Daval Cub Trade Stimulator

This is a great antique Trade Stimulator I've just purchased at an antique show. 1940ish Daval Cub. Disguised as a gumball vending machine, but was actually used for illegal gambling back in the day. Operates as a slot machine. Insert one penny, and spin the reels. If you matched three identical packages of cigarettes, the shop owner, or bartender would give you a free package of cigarettes. However to try and get around the gambling laws, each penny would dispense a single gumball, so you got something for your penny.
