My initial thought is that this is a restock. I did some looking and found an entry in Jerry Noble's book, Notes on Southern Long Rifles, Volume 1, where he mentions a B. Bean for E Walling, probably Elisha Walling. He said the rifle has been restocked in the last 40 years but doesn't mention who restocked it. He also mentions that the account book of Thomas Amis of Big Creek, Hawkins County Tennessee mentions Elisha Walling in 1786. This is on page 19, Volume 1. Is it the same rifle? Probably.
