Here's what I've got Chuck. The forearm does not match the stock very well, which is very nice, as you can see. There is a sizable chip out of the bottom of the wrist alongside the lower tang, but I'm not going to do anything about it. Call it patina.
No marks at all at the breech end of the barrel. It is an early SBT, 177853, I think (from memory). I have only seen one earlier and that was in the pages of the Parker magazine.
Not the best focus, but you can see it's an early SBT and obviously a SC.
