Major project? Depends. If the barrels are no good then yes, to me it would be a major project and one that I won't deal with. Like having to sleeve because of pitting or too thin walls. But IF the barrels are good. And i do have the tools to measure wall thickness choke and chambers, then to me it isn't a major project. I can do all metal work including Damascus refinishing. So what's left is the wood. Which yes of course has issues. I have already spoken with two wood people and they so far agree with me that a butt transplant will be the best cost effective fix. But until I actually get the gun in hand no decision made on it yet.
So I'm in it so far for 600. If I go the transplant route for 800 and I don't count my time on metal and Damascus refinishing cause it's free to me, is it a 1500 gun? I don't know I dont care.
