Along with all the other details that may help identify the gun, or at least its most likely origin, the tang is an important detail on many of these mountain rifles, with a number of different styles used in different Appalachian areas So, when you are getting all the other pictures of details on the rifle, please get a full/complete picture of the tang behind the breech end of the barrel.
Also, another easy question... is the nose cap out by the muzzle open on its outer end so some wood shows between the bottom of the barrel and the nose cap, or is it closed so no wood shows at all? This detail can also help us locate the gun better.
Neat rifle, and as mentioned above, it has survived in better shape than many backwoods Appalachian mountain guns. I'm a little jealous!
