The lock is signed "POTZDAMMAGAZ" at the center and "S+D" at the middle of the lower beveled edge. Per George Moller in "American Military Shoulder Arms, Volume I: Colonial and Revolutionary War Arms", the latter indicates it was manufactured before 1775 while the arsenal was owned and operated by Splittgerber & Daum, the most powerful company in Prussia. The barrel has a bayonet stud on the bottom near the muzzle, a rounded brass blade front sight, and Spandau proofs at the breech. The furniture is brass and is robustly built. The side plate and buttplate tang are marked "179." The wrist escutcheon has the cipher of Frederick II of Prussia (r. 1740-1786). The trigger guard and buttplate have spire style finials, and the stock has raised relief spear head style carving and molding and the "cow's foot" style butt. A "4X" marking is on the left flat, and Moller's faint "GDM" collection mark is by the toe. It has a heavy iron ramrod and an old leather sling. The socket bayonet is unmarked and is a very tight fit. Provenance: The George Moller Collection
