This gun is featured and discussed on pages 81-83 of "American Military Shoulder Arms, Volume 1: Colonial and Revolutionary War Arms" by George Moller where it is listed as an "Assembled Club Butt Fowler" and noted as having influence from the French buccaneer gun and built with a lock from a British musket from 1700-1715. He also notes that the 20th Regiment marking on the barrel dates the "barrel at 1753 or later, when British muskets were marked with regimental numbers." "It might well be categorized as a colonial musket assembled from salvaged British musket components, except that the barrel is quite long and it has no provision for a bayonet." The barrel has a rounded blade front sight and is marked "XX-REGT." on top in the breech section and has faint Ordnance Department markings. The lock originally had a back catch and appears to have be marked "R/ALLIN" at center. The furniture is brass aside from the iron trigger guard. The stock has the distinctive club butt profile, and a small "GDM" collection stamp is near the toe. Provenance: The George Moller Collection
