The pistol and extra lock are likely pictured as part of "The Simeon North Collection of Guns" (third from the top and bottom right respectively) 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." The two locks would have originally been interchangeable, a feat first guaranteed by North on the Model 1813 just a few years earlier. The double strap barrel band has a brass blade front sight. The barrel has "P" and "US" on the left at the breech. The locks have "S. NORTH/U[eagle]S/MIDLN CON." (faint on the extra lock) at center. The stock has a faint outline of a cartouche on the left. A hickory ramrod is fitted beneath the barrel.
