.58 caliber. 34.5" pinned three-stage octagon to round barrel with baluster turned rings at the transitions. SN: NSN. Blued finish, brass and iron furniture, walnut stock. Pointed tail lock appears to be in original flint with rounded iron pan that is fenced and bridled with a rounded swan neck cock and possibly replaced top jaw and screw. Lock marked in two arched vertical lines at the tail "SARGANT/& SON" and with the American Fur Company trademark "{Tombstone Fox}/IA" under the pan, over the word "WARRANTED". Barrel marked "LONDON" on the top flat and with another American Fur Company mark and a set of post-1813 Birmingham commercial proof marks. Typical Northwest Trade Gun features including serpent side plate, over sized iron triggerguard, carved moldings around the lock mortise, counterpane and tang and simple screw retained flat brass buttplate. Ribbed brass pipes retain an old, brass tipped  wooden ramrod. A solid example of a 19th century flintlock trade gun. The firm of Sargant & Son started to do business with the American Fur Company circa 1836 with the correspondence indicating a change in name to Sargant & Brothers circa 1840. They continued to provide guns to the American Fur Company through the early 1850s.
