The pistol appears to be the one shown in the middle right of the picture of "The Simeon North Collection of Guns" that was donated by North's great-grandson Ralph H. North to The Franklin Institute and shown in the 1944 article "The Origin of Interchangeable Parts" by Thomas Coulson, Director of Museum Research at The Franklin Institute. North was co-author of "Simeon North: First Official Pistol Maker of the United States." Only approximately 1,626 of these pistols were manufactured c. 1813-1815 before the military decided .69 caliber loads produced excessive recoil, and they are significant as the first martial arms contracted to have interchangeable parts, a industrial innovation North was crucial in developing. The center of the lock has "S. NORTH" in a downward arch over "U [eagle] S" and then faded "MIDLN CON" markings in an upward arch. The barrel has "P/US" on the left at the breech. The furniture is all iron.
