Can you tell us which mounts are brass, and which are iron, on this rifle? The butt plate and pipes "seem" to be iron in the photos, but can't tell about the guard.
At first blush, I'd place this rifle in the far southeastern Kentucky Cumberland Plateau region near the Tennessee border, perhaps Harlan, Letcher or Leslie Counties or thereabouts. The more conventional rear pipe and butt plate with shorter return, extended tang, silver barrel plate, tight side facings, simple cheekpiece with single molding line, pinned butt plate tail, etc., all are characteristics of guns from that area. The strongly pointed toe on the butt seems more Tennessee in style, but some rifles in far southeastern KY used nearby TN details such as the exaggerated toe in later years. This should prove to be another interesting rifle to discuss and try to locate. Thanks for posting.
