Iron lock with teat at rear marked HARPERS / FERRY / 1807 in three lines at tail and with spread-winged eagle over US between the flat reinforced cock and the pan.

This pistol is reference on page 35 of Rick Hudak's Harper's Ferry Arsenal and Joseph Perkins - The Classic Arms of the Early Years.
About good overall. A very high quality re-conversion to flint. Significant pitting at breech and touch hole, typical of percussion flash erosion. Pan re-welded to lock, associated flintlock battery replaced. Mechanically functional. Barrel and lock with a deep plum brown patina. Brass lightly cleaned to bright. Stock about good as repaired and refinished, with a break through the grip artfully repaired and another through the lock mortise cleanly repaired as well. A very attractive pistol that displays like 5-figure gun without the associated cost.
