.58 caliber. 31.75" three-stage octagon to round barrel. SN: NSN. Heavily oxidized metal, brass furniture, period shortened stock. Percussion altered lock dated "1855" at tail and marked with a "{Circle-Fox}" forward of the hammer and secured by only a single remaining screw. Barrel shortened during the period of use with stock cut back to a "half-stock" configuration with a crudely applied blacksmith made iron strap barrel band secured by a single nail. Traditional trade gun features include the cast "serpent" side plate and flat, two screw buttplate. One of the original corrugated ramrod pipes has been soldered on to the bottom of the barrel about 3" from the muzzle. A real example of a period altered and modified Northwest trade gun that saw heavy use during the mid-19th century.
