Wildcatter,
Like Eric, I see a lot of Upper Susquehanna influence in your rifle. It's easier to point out features that are not commonly seen on guns from that area. The fact that it's not stocked in maple is unusual. The wood appears to be walnut. Up-the-river longrifles in walnut are not unheard... just not common. The side opening patch-box is rarely seen on guns from the Union / Snyder County, PA area. The patch-box release button through the toeplate is also uncommon on guns from this area. Other than these features, this gun looks like many others I've seen from the Upper Susquehanna school. I'm curious what others have seen about this gun that makes them think it is a restock? I like the sideplate for the lockbolt. To me it looks like a comet shooting over the moon inlay. The top ramrod pipe looks longer than the other pipe (?). Was it possibly replaced? Does the inlay under the cheekrest include a touch-hole pick holder? If so, this could indicate that the gun was originally flintlock. Does the lock mortise appear to have been made for the lock that is currently on the gun? Thanks for posting the photos. Mark
