No history that I know of. It's owned by a couple of wealthy women, who knew the maker and had apparently done some research, but I forget his name. I offered advice about cleaning it up and further offered to get it photoed for submission to Muzzleloader, and they expressed some interest, but never called me back. It had all the bells and whistles, and a early American Eagle inlet (the skinny kind of bird). It had lots of handling marks on it, and the patchbox had been polished with brasso, as you can tell from the screw heads.
