.56 caliber. 36" pinned three-stage octagon to round barrel. SN: NSN. Bright finish, brass and iron furniture, full-length walnut stock. Lock from a British military Type III Pattern 1853 Enfield and marked "1856/TOWER" forward of the hammer, along with a War Department "{Crown-Broad Arrow}" and with the British "{CROWN}/VR" at the tail. No visible barrel proofs. Three-screw brass serpent side plate, oversized iron triggerguard, flat brass buttplate with five screws. Two corrugated ramrod pipes with old iron trumpet head ramrod. Stock with traditional raised carved aprons around the tang, rear of the lock mortise and the counterpane. A nice example of a mid-19th century trade gun, showing the evolution from the 18th century form to the more "Enfield" inspired form of the late 1850s through the turn of the century, retaining the early barrel form, stock and side plate but adopting the new standard of the Enfield percussion lock.
