The rifle has Ohio characteristics. The triggerguard and butt plate are commonly found on Ohio rifles. Buckeye rifles tend to have many metal ornaments rather than carving. The stepped rear sight suggests to me post CW build. As I recall Studebaker displayed at the 1876 centennial exposition a wagon fitted with all aluminum metal part. It was considered as one of the most advanced uses of aluminum at the time. In those days aluminum was very uncommon, expensive, and just beginning to be worked commercially. That makes me think in its day the rifle was a high dollar piece. I'm inclined to think the ornaments were made by someone like Tryon, who supplied metal fittings to gunsmiths.
