This gun is in very good condition and exhibits the correct Hudson Bay Co. stamping to include the tombtone seated Fox over EB on the lock and the half inch circle with the seated Fox on the stock. The fox is mostly gone. The gun was converted to percussion during it's period of use. The lock is signed Parker , Field & Co. 1856 on it's tail area .  The 36 1/2" barrel has two British proof marks at it's breech. The lock functions properly on both full and half cock. Overall the gun has taken on a nice golden patina.  Sitting Bull  owned a Parker Field & Co.  trade Gun.  It just sold for $162,500 at Heritage auctions.
