If you find a decent donor stock, for the head part, I would think it could be done just to save a great looking butt stock. I had a Belgian Guild gun which had a full wrist fracture, which I thought about just having a new wrist and head stock inlet then save the fancy butt stock to graft into it. Ended up doing a glass bed repair with new billets of French walnut to fix the broken center structure. Used the gun for a season with no problems. I tried the repair because I did not want to I let the new wood. Sometimes you can fix them and sometimes they just need to be lamps.
