I would buy that in a heartbeat !
I have the blued/walnut M70 Alaskan, assembled in Portugal. I've also had the Whitworth.375 and loved the feel of the stock and handling but the Winchester I can cycle the bolt effortlessly from the shoulder for quick follow up shots, not so with the Whitworth, I get a jam in feeding half the time on the second round.
My .458 Whitworth is no problem from the shoulder in cycling the next round. I guess the extra 3/8 inch or so bolt travel, with M98 geometry and my gangly arms makes a difference.
I saw these stainless,/laminate M70s a while back and should have jumped on that.
Good Luck with your purchase.
