puzzler???

At a recent estate sale I bought a gun case W/ rifle in it we were biding blind. Some times I get lucky and felt so and bid high. The gun is black powder .50 mountian man style. the nipple is very large,
There are 2 bars holding the barrel down, double trigger,rocky mountian style sights and the MOST prime peice of wood i've ever seen in my life A tiger strip dark beauty. the only markings is a name on the left side of the barrel WARREN DOBB and the left side has #8333.
Might anybody know the value on this weapon??
