This large blunderbuss is approximately 4 bore and flares to just under 2 inches at the muzzle. It is pictured and discussed on pages 280-283 of "American Military Shoulder Arms, Volume I: Colonial and Revolutionary War Arms" by George Moller and has his small "GDM" collection mark by the toe. He notes: "The lock of this blunderbuss is dated '20,' the last two numerals of the year 1720. Like many blunderbusses made before the middle of the 18th century, it has a brass barrel dating from the late 1680s, salvaged from an earlier arm." The barrel has William III era proofs, an unclear maker's mark, and "44" on the breech section. The bridle-less lock has the early Georgian cipher at the center and "TOWER/20" on the tail. The plate is flat and is secured by three screws. The inside has "crown/30," "P," and "18" marks. The stock has a storekeeper mark on the right, "crown/10" behind the trigger guard, and brass furniture. Provenance: The George Moller Collection
