.58 caliber. 36" pinned three-stage octagon to round barrel. SN: NSN.  Oxidized metal, brass and iron furniture, full-length walnut stock. 6" flint lock in original flint configuration and marked "WILLETS" at the tail and with the "{Circle-Fox}" trademark under the pan. Lock with fenced, unbridled pan and swan neck cock. Top flat of barrel with another "{Circle-Fox}" trademark and marked "MINORIES LONDON". Left angled breech flat marked with pre-1813 raised London commercial proofs in depressed ovals with the maker mark "*/RW" for Richard Wilson. Typical trade gun features include the three-screw "serpent" side plate, oversized triggergauard, flat nailed buttplate, and corrugated brass pipes. Breech tang screw enters from the bottom of the gun. An indecipherable maker's name is present in the ramrod channel. Includes a brass tipped wood ramrod. The somewhat ill fit of the lock suggests that it is a replacement, and the gun is probably really a Wilson, rather than Willets' produced trade gun. A lovely early gun.
