The black powder rifles seem to be slowly creeping up in price. I remember when it was very difficult to sell one regardless of who's name was on the barrel. I will make a stab at pricing the rifle but due to the fact that I don't have it in front of me, I can't promise anything but an educated guess. If the gun is in the condition that you mentioned, it should easily bring 5500-6500. Some dealers will ask a lot more but again there are not a huge amount of buyers for the bpe rifles. You also neglected to say if the gun was cased? Does it have tools? These will increase the value of the rifle. Again this is just a guess.
