Noble vol. 1 (p. 105) has him from Kentucky originally (I'd take that with a grain of salt), along with some few other details, most of which you have. At first glance, I don't think it looks very Bull-ish, either, but I wouldn't rule out N. Alabama/Middle TN. -- traits from Va. and NC, etc., are often mixed and matched, it seems to me. One thing that may confuse the issue is if the maker is known for iron mounts and builds something with brass mounts (maybe even bought from elsewhere), it may look quite different?
