Nice score. I like your idea of the oberndorf bottom metal, change the bolt handle to a long either straight or slightly bent oberndorf tear drop bolt handle, remove the charger hump. It looks like it already has a mdl 70 style safety.
If the feed rails have been modified and the cost to repair is too high. I would leave as is if it shot ok or turn it into a 284 winchester. I like the 284 even though I have never owned one.
Good luck with your project. Heck it's still nice if you don't do anything to it.
Agree.
The .284 family of rounds are good ones, although not the most popular.
