Recently, a friend who lives out West asked me if I could answer some questions about this muzzleloading double. His neighbor knocked on his door and gave it to him more or less out of the blue. The neighbor knew only that the gun was made in New York, “in one of the prisons” sometime in the early 1900s. It’s a 12 gauge percussion-gun, with fluid steel barrels, a curly maple stock, and hand engraving, including the steel buttplate. The only markings on it anywhere are a very faint lettering that looks like “M.H.” It’s in such good shape; my friend says he’d have no qualms about shooting it right now.
