This exceptionally large ring was offered in 1951. The cannon barrel comes in an aluminum variety as well as this brass variety. The base on both varieties is brass with adjustable bands picturing the Quaker man logo on one side while opposite shows cereal grains shooting from a cannon barrel. Mounted on the ring top is a black metal frame with red plastic segment surrounding the barrel. Cannon has spring loaded plunger which when pulled out serves to shoot objects dropped into the barrel out into space. Exceptional example, essentially Mint. Works great.
