The lock plate is stamped with the vertical date "BARNETT/LONDON/1875" behind the cock and the sitting fox over "EB" (Edward Bond) stamp below the pan and on the top barrel flat at the breech. The barrel also has a "JEB" (John Edward Barnett) maker's mark, flag, and London proofs. The Barnett family supplied the Northwest Company and then the Hudson Bay Company from 1842 to 1875. The trade had slowed tremendously by mid-century making extremely late examples like this rare.

Fine with a mottled gray and brown patina overall, some light oxidation and pitting, generally fairly light wear on the metal, a crackled protective varnish finish on the stock, a minor crack at the tail of the lock, small flake by the barrel tang, and mostly limited storage type wear. Mechanically fine. This is a very attractive example of a traditional Northwest Trade Gun dating to the year before the Battle of Little Bighorn. It is difficult to find these Native American trade guns in original flintlock configuration and solid condition.
