As Greywuuf said, the rifle he is researching is NOT a Hawken. The rifle was made by W. Ogden of Owego, New York. Following is information on the rifle in question, from the Museum of the Mountainman website. http://museumofthemountainman.com/jim-bridgers-rifle/
JIM BRIDGER’S RIFLE
In 1853, Louis Vasquez a good friend and business partner of Jim Bridger, had this 40 caliber half-stock rifle engraved J. Bridger 1853, and presented it to Jim for reasons still unknown. Perhaps it had something to do with their long business association or possibly it was due to the fact that 1853 was indeed a turning point in Jim Bridger’s life.
Following Bridger’s death the rifle was held as part of a private Buffalo Bill Collection. In 1940 the scout’s rifle and the powder horn were put to auction by Theodore Dexter, then one of the most notable rare-arms dealer in the United States, and it stayed in the private collection of Mr. A. W. McCollough of Laramie, Wyoming until 1968. Rare-arms dealer Robert Nelson of Cheyenne, Wyoming purchased the Bridger Rifle in 1968 but subsequently sold it to another dealer in Texas where it has remained until it found a permanent home in the Museum of the Mountain Man in 1988.
This half-stock, percussion plains rifle is bored .403 Caliber (rifled). It carries a pewter fore-end cap, brass trim, “plains” style trigger guard, H.T. Cooper back-action lock, and hickory ramrod. The rifle’s walnut stock is decorated with inlain eagles, the left eagle engraved, “J. Bridger 1853.” An unusual feature is that its stock was built with two cheekpieces. Riflemaker W. Ogden of Owego, New York stamped his name on the barrel. It weighs eleven pounds and its overall length is 49-1/2 inches.
