I call this a Chunk Gun. I don't have a real clue what to call it.. The only marks are on the rear sight. It is a Marble with no visible number and the patent date is illegible. It is about .45 cal with a sweet bore. Appraising for a friend who lost his brother. Information and ball park values please. The stock crack is serious and will be properly fixed. Missing the false muzzle.
