Doug and Pete-

Thanks so much for joining me in my head scratching! The lack of maker's mark made me wonder if this might not have been of domestic (American) manufacture. However the numbering of the locks to the barrel seem to indicate some organization, and the carving work looks very Germanic. Maybe made by a German immigrant? I had hoped that the proof mark would catch someone's eye as one they recognized. Looks like this old gun may remain a mystery.
