That one would be a real test of a restorer's skill. Replacing the recoil pad with a butt plate would leave the stock too short for most people I should think. I doubt Barney had a heavy hand with a buffing wheel so as to blur the receiver markings, which prompts me to wonder if it hasn't gone through one 'restoration' already, in the hands of Bubba. Is it my imagination or does it appear to have originally had a G&H side mount, replaced with the ever more proletarian Weaver side mount?
I'm not one to post a query concerning a current auction (preferring to discuss such things in private), but since the 'cat's out of the bag' it does pose some interesting points of discussion.
