I have a chance to buy a 1962 production M70 FWT in .270. Photos show a little fading of the blue and flaking of the wood finish. Butt plate has been replaced w/ a vented pad, a long time ago. Comes w/ Leupold Dual Dovetails and a leather carry strap, also obviously very aged. He's asking $775. I don't think I can get hurt (financially) on this. Opinions?
