Nice post, TN Rifle. You've taken good care of that rifle.
I remember the "Plainsman" rifles in the Dixie Gun Works catalogs back in the sixties. I believe Dixie provided a physical description of the rifle and a little spiel about plains rifles in general, with comments lifted out of Hanson's book. However, I don't remember Dixie mentioning who made the rifles. In any event, it looks like a good, solid shooter.
I wanted one of those in a bad way when I was a teenager. It's great that you got one, and that you still have it!
