Hello! New member here - my father in-law passed on and since I have a variety of firearms the family handed me his JM Brown Percussion Shotgun. It's been in the family for three generations as far as they know but the family knows little of it's history and I am not finding much online about them. I presume its a mid 1800's based on the technology but that is purely a guess. Looks like someone tried to weld a repair between the barrels and its missing the ramrod. Questions - where can I go to learn more about them? Are they worth restoring / reconditioning? Thanks!
