We almost had an unfriendly meeting. If you had cut that barrel WITHOUT the dent in it I would've been irrate. I have one, from 1911 I believe, and while it needs a new stock it is in otherwise "perfect" condition (not "pristine"..."perfect"...meaning no pitting and that lovely even brown patina over the whole thing.)
I've looked for barrels, there is something different between the Mo. 11 barrels and A-5 barrels that means you have to find an actual Remington barrel. I don't know if the Savage barrels will work. (I'm sure they'd be even HARDER to find.) I know the A-5 stocks won't work either...how I wish they would!!!
Hurray for technology that allows us to buy the cool new-fangled "pl-pl-pl-pl-pl-pl-ploooom" guns that can saw trees in half, and the hurray for the classic "ploo-chick, ploo-chick, ploo-chick" guns that make you look forward to reloading!
