Here are the brls on Troney's gun, which are indeed what Hunter Arms called 'Good Damascus' and which are 'Two Iron Crolle' I can certainly see the 'B' which may be followed by a '&' and a letter? Likely distributor marks, and the 'Bs' I'm aware of are: Boehme & Rauch (Monroe, Mich.), Bolles-Brendamour (Cincinnati), and Belknap Hardware Co. (Louisville) Any thoughts or similar marks on someone's gun?
