.54 caliber smoothbore, 57.25" octagonal-to-round barrel, full stocked with simple raised cheek piece and flat toe line. Steeped flat waterproof iron lock with roller frizzen marked with flat swan necked cock, both lock and cock lightly engraved. Top of barrel flat marked near lock, dovetailed notched rear sight, dovetailed blade front sight. Classic southern "poor boy" construction without buttplate, nail secured iron trigger guard. Wooden ramrod.
Very good, likely a re-conversion to flint from percussion, as pitting around the breech is not typical of flintlock arms. Mottled light and dark gray patina on barrel, moderate pitting at breech, rest mostly smooth. Lock mechanically functional, bore fair to good. Original iron pipe in lower position, replaced brass pipe in upper position. Stock with nicks and dings and some wood loss on the reverse near the muzzle and cracks along upper edge of stock on reverse.
