Reportedly, 9,440 British muskets were imported to Philadelphia circa 1799-1800 and placed in the Schuylkill Arsenal. Some of these were likely from the Revolutionary War, but others were imported new. India pattern Brown Bess muskets imported for U.S. use in the early national period are discussed on pages 3 and 4 of "American Military Shoulder Arms, Volume 2: From the 1790s to the End of the Flintlock Period" by George D. Moller. Moller states, "There are very few early India pattern muskets with 'US' markings in American collections." British proofs and "US/S.N.Y" marked on the barrel at the breech. "US" marked on the tail of the lock with "TOWER" and the standard Georgian cipher markings, "TK" inspection mark behind the lower tang, and a small "TC" on the left flat. Later converted from flintlock to percussion.
