An 18th century flintlock blunderbuss pistol signed 'Barnett' circa 1760-1780

Having a 6 1/4" cannon form brass barrel with a 1" muzzle, this interesting example has a sliding safety. The Engraved brass trigger guard ends with an acorn finial. The walnut stock is fine with no cracks or repairs and has checkered grips with a silver butt cap. Mechanically sound. The cock appears to be a later replacement. Overall length: 10 3/4"
