I just purchased this at a local gunstore. They had it on the rack listed as a wallhanger which it is, $39.99 was the asking price. I look at it and I think trade gun, perhaps with some Indian ownership. Hard to prove, but this area has lot's of reservations and it had been part of a collection of someone who was in the area for a lifetime. In any event, it was an oddity that I didn't mind spending a couple 20's on to obtain. Here's some of the pictures. If you look close you can make out the outline of the pan on the percussion lock left over from when they converted it to a percussion, the touchole is also still in the barrel and I don't know if it was ever plugged or not. The gun is also still loaded, I found this when I dropped a ramrod down the bore to check, something to keep in mind when dealing with guns, especially old ones like this. I tried to remove the charge with C02, but that failed. My only other option is to pull it with a screw attachment, I'm not going to try and remove the breech on this thing. Tell me what you think, I have only a general idea what kind of musket it might have at one time been.
