hurricane,
Well I won't argue with the experts either, but it's certainly true that stray parts have found new homes,,, some honestly as in period restocks, and others not so honestly.
I have a few old buttstocks. Some have most of the brass, most are just stripped bare. Doubt the brass was turned in at the recyclers, but then again I don't know for sure what happened to it.
As for this one, being broken where it is would make it an easy repair. BUT adding new wood to old wood in a convincing and invisible manner is not something that just anyone can do, not to mention matching the color and conditions of the original part. Anyone that can do that quality of work would charge more than the gun would be worth, and done to a lesser degree it'll be obvious to all but the blind.
As far a scooter opinion, yeah, I'd rather own this buttstock restored than some plain jane generic rifle for the same amount of money. Like he said, for the most part what you're paying for is from the lock back!
