Yes - it appears to be related to at least three other known guns - the one in the virtual libraray, one from the Bill Ivey book, and one that another ALR member posted a ways back that was found near Maryville, TN. A pretty distinctive style.
I could be wrong but my gut feeling on these is that they are from somewhere near the Great Smokies region - could be either side of the NC/TN line - they don't look like upper East TN to me in the sense of the rifles from Unicoi, Sullivan or Washington County areas and I think they were made a little farther south.
Whoever this gunmaker was, i really like his work.
