William Barnhart Sr. (1802-1867) was a talented gunmaker born in Pennsylvania and who worked in Ross County, Ohio. The rifle has traditional blade and notch sights, "W. Barnhart 1838 S" signed in a silver inscription panel on the top of the barrel, converted "J. BISHOP/WARRANTED" marked lock with scroll engraving, double set triggers, brass furniture, a pierced and elaborately engraved patch box, scroll and floral engraved brass wear plate as well as incise carved scroll accents on the forend, and engraved silver side plate as well as 13 engraved silver accents including a patriotic shield on the wrist and spread wing eagle and shield on the cheek which has a prominent raised relief carved scroll pattern.

Very good with dark brown patina on the lock and barrel, moderate flash pitting concentrated at the breech, some tool marks and edge wear, aged patinas on the silver and brass, crisp markings and engraving, and mild overall wear. The stock is good and has a small repair above the nose of the lock, a break through the lock mortise and replacement plate ahead of the trigger guard, beautiful flame figure, minor scratches and pressure marks, and crisp carving. The lower patch box plate is a replacement. Mechanically fine.
