I ran across a Marlin Model 55 Goose Gun last Friday at a garage sale in Vancouver. Chambered in 12 ga 3" magnum. Pretty good shape. Bolt action with a 2-shot magazine. Dang barrel is about 30" or so. Haven't measured it yet. The guy was asking $100 but finally let me have it for $80. I don't hunt geese or ducks, but it seemed like a good deal. Maybe a turkey gun. Maybe I can make a few $$ or swap it for something.
