The rifle has a slight "fish belly" in the butt's lower toe line, which is most often seen on Ohio or Indiana guns. The guard on this rifle has a "square shoulder" above the rear spur where it meets the rear extension; that detail is most often found on guards sold in or near Louisville on the Ohio River. The side facings are pointed on the front end; that detail is found in the midwest, often in KY and IN but also in other states. The long three screw tang is usually found on the south side of the Ohio River and is considered a "southern" detail. It would be helpful to know the barrel length and bore size...and without desassembling the rifle to make sure, I'd guess its barrel has been shortened a couple of inches based on the rear sight location. If the maker marked this gun, there would be a name, or initials, several inches behind the rear sight on top of the barrel. Shelby Gallien
