Looks like a good candidate for being an organ donor! Barrel is too rough on outside for anything but complete re-polish or replacement, wood nothing to brag about, and the rear sight is missing (and quite expensive to replace.) It looks like someone has started polishing on the receiver (left side) as well. The good news is that the muskets ALL had large barrel shanks (AFAIK) and the receiver itself doesn't look too badly pitted to polish out the rest of the way. I would look at it as an action waiting to be built into a nice custom 'wall, but YMMV!!
