.58 caliber. 42.25" pinned, three-stage octagon to round barrel with baluster turned rings at the transitions. SN: NSN. Bright finish, brass and iron furniture, walnut stock. Commercial flint lock appears reconverted with a replaced pan, is lightly engraved with simple floral motifs under the pan, at the tail and on the hammer neck and is unmarked externally but is marked "T KETLAND" on the interior. Barrel is marked on the upper left angled flat with pre-1813 London commercial proof marks and the "*/TB" maker's mark of Thomas Barnett. Traditional Northwest gun features include the serpent side plate, large triggerguard, carved moldings around the tail of the lock, counterpane and breech plug tang. Early production features include the thin, nailed brass buttplate and the tang screw entering from the bottom of the stock forward of the triggerguard. Butt with the letters "W" and "X" carved on the reverse. It is not clear if the Ketland commercial lock was used by Barnett in the production of the gun or if it was a later replacement. Barnett was one of the most prolific of the English gun makers to produce Northwest Trade Guns.
