Nice rifle. Looks like it was sporterized at one point.
Ouch! It pains me to see one that's been cut like that. It's not a commercial sporter so the value is pretty much what you are willing to pay for it. Restoration is possible - and the value would not be lessened, IMHO. It just won't be worth what a "regular" rifle would be worth, either. It looks like it is in very nice condition - enjoy it!!
