Sorry for coking late to the party, I was on a hunt in Oklahoma.
It look like a parts gun but the barrel looks like a real NM barrel - where would they ever get one of those? The floor plate looks to worn for the condition of the stock??? If that's an original NM stock and it hadn't had the grip cap added to it the value of the stock alone would have easily been $1000 IMHO as you just will never find another NM stock - ever!
As was said if it were mine I would enjoy it as is or build it into a 35 Whelen, but that's just me.
I'm flattered that people defer to me on M70's but I'm more into Pre-war and transition than post war guns. My post wars are used more for hunting although I'm real tempted to pull out my transition 257 SG Carbine next year for deer.
