Manufactured in 1861-1900. The famous Northwest Trade Gun was the primary firearm of the fur trade and continued to be supplied to Native Americans until the end of the 19th century and saw use in various battles, including the Battle of the Little Bighorn alongside more modern firearms. This late period example has a Enfield style percussion lock and bolster but otherwise remains mostly like the trade guns built for decades. It has a small blade front sight, smoothbore barrel with incised transition bands and Birmingham proof marks flanking the 26 bore mark, "I. HOLLIS & SONS" on the lock and "MAKERS TO HER MAJESTY'S/WAR DEPARTMENT" around the "IHS" monogram logo on the tail of the lock, tear drop flats, large iron trigger guard, classic Northwest gun serpent side plate, and wire banding towards the forend tip, and four brass tacks.

Very fine and well above average for a Northwest Trade Gun with 40% original blue and casehardened finish, gray and brown patina on the balance of the steel, minor oxidation, aged patina on the brass, and mostly only age and storage related wear. The stock is also very fine and retains most of the original finish and has minor scratches and dings. Mechanically fine.
