This musket is pictured and discussed on pages 429-432 of "American Military Shoulder Arms, Volume I: Colonial and Revolutionary War Arms" by George D. Moller, and Moller's "GDM" collection mark is discreetly marked by the toe. The lock plate is marked "POTSDAMMAGAZ" and "D S E" indicating that it was manufactured under the direction of the firm David Splitgerber Erben under the leadership of Splitgerber's son-in-laws at the Potsdam Arsenal in 1775-1795. They were the successors (erben = heir) of Splitgerber & Daum, Prussia's largest mercantile firm in the 18th century. The wrist escutcheon has the cipher of Frederick the Great further narrowing the production range to 1775-1786. The trigger plate has a "W" mark, and there are some slightly obscured eagle proof marks and an incomplete cartouche on the barrel. It has primarily brass furniture including the distinctively shaped brass ramrod pipes, a Prussian serpentine style side plate, and long, sculpted trigger guard. It is fitted with a nearly full length stock with "cows foot" butt, a long sculpted buttplate tang, and sling swivels with a black leather sling. The barrel is fitted with a brass blade sight on top and bayonet stud on the bottom, and a steel trumpet headed ramrod and socket bayonet are included. Provenance: The George Moller Collection
