If the barrels are okay, that stock can be replaced with a duplicate for a fairly small cost. Talk to Dick Greensides at Pecatonica about making a copy from the wood you have. You will have to piece it together, and glue it, in order for him to have something to duplicate, but duplicating the original stock will save lots of time in inletting and finishing the stock. Those back Action locks were used from just around the Civil War, to about the turn of the century. They were available as parts in hardware stores clear up past WWII. I think you can still get the actions and parts from Dixie, or " Gun Parts Corp."
It certainly is worth what you paid for it, and probably more. With the history you already have for the gun, it would be worth restoring. You can find another trigger guard for you chunk gun. :hatsoff:
