It shipped as a 308 "AB" S22LL the second most common non prefix.
Nothing was correct with the exception of the serial number. The butt stock was cutt. So evev if you had the correctrecoil pad, you would still need a butt stcck with the correct period shape, finish and checkering pattern. Then you would have needed a SenMi Beavertail forearm with the correct "A" inletting. Then the correct Douglas 308 barrel.
Even if you had everything the lilelyhood the date stamps in the stocvk would be correct would be almost zero.
So when you got done you'd have a cobbled together rifle that nothing marches on, even if period correct.
As one meber pointed out, it's either a factory original correct rifle, or it isn't. This one can nevr be, which is why so many serious #1s guys thhat looked at it, passed.
Get done and you'll have an $800 shooter. After spending $500 - $800 not counting the purchase of the rifle.
If you sell it are you going to tell the purchaser, oh by the way, it's got a replaced stock, butt pad and barrel, which would be the only honest thing to do.
I looked several times but starting with the cut/shortened butt stock and then.......................................while doable, not worth the effort just to say you have a 3 digit #1.
