Tennessee Rifle from Library and this one I have

[wildcatter]

I have been researching this rifle for many years, trying to figure out where it originated. I happened to be searching the library again hoping to find something. I guess I had never scrolled all the way down in the iron mounted unknown section because last night I found this rifle and boy the one I have and the one I this link sure look very similar: http://americanlongrifles.org/forum/index.php?topic=11873.0. Barrel tang, cheek rest, triggers, trigger guard (except mine isn't rounded). My pictures are below. Any ideas on what part of Tennessee they both could be from?
