Some of the most interesting firearms I've seen have been antiques. For example... A black powder double barrel shotgun, A lever action Henry with a brass receiver & octagon barrel (not the modern version) and one my father had given me when I was a kid. It is a Merwin & Hulbert double action, .32 S&W long, 7 shot revolver circa 1860. The workmanship is incredible. I don't even know how they made something so precise back then.
