I saw this at a gun show today for $250. New in the box. I don't think the barrel was ever in the stock except at the factory.
50 caliber Hawken.
All blued and highly polished patchbox, buttplate, lock, barrel, etc. They were almost black and like mirrors.
The stock was about the nicest piece of burl walnut I ever saw on a T/C rifle.
Both the box and the barrel said custom 50 Hawken.
I almost bought it but I knew it would just sit in the closet forever.
