.... A GOOD ONE, Jim,... !!!! .... if you go back to a post here of January 30, 2021, in a topic started by Longknife entitled "Southern Rifle, Unknown Maker" .... you will see this gun's sister,... same initials, followed by a date of 1886 on the barrel,.. he found it up in Monroe Co. TN and it has same features as yours,... I recollect this one because of the association with Sam Burchfield of Cades Cove,.... hope this draws a lot of discussion,... interesting rifle,...
