The Model 1842 was the first standard U.S. martial pistol produced originally as a percussion weapon and was used primarily in the Mexican-American War with service into the Civil War era. This example was manufactured by Henry Aston & Co. and features two distinct oval script "NWP" (Nahum W. Patch) and "WAT" (William A. Thornton) inspection cartouches surrounding "W.C.K." inspection initials which are repeated on the right of the breech, "1847" dated lock and "1848" dated barrel tang, marked "US/NWP/P" on top of the breech. Provenance: Richard Peters, USMC, Reserves Law Enforcement, a Gentleman

Fine, with the iron surfaces polished bright showing some faded edges on the markings, some scattered minor surface pitting, and bright golden patina on the brass. The stock is excellent with distinct edges overall, attractive original raised grain, a few light dents and handling marks, and exceptionally crisp cartouches. Mechanically excellent.
