I wonder how the type of the steel used in the receivers changed from pre-war production to post-war and then to post-'64? They changed the manufacturing methods and I'd bet the steel too.

You can find out if you'd be willing to fund the metalurgical analysis and provide samples. It's not terribly expensive, a friend recently had some coins checked for content though it was via a friend with access to the equipment.
I think the more dramatic differences will be in the consistency of the steel from lot to lot, the accuracy of the additives to the steel and the accuracy of the heat treatment and post processing. We've had to tighten up the slop because iron and additive metals are getting expensive. For post processing we have to make sure every scrap of the chemicals are actually used so that disposal is less of a problem.
You might ask Winchester if they'd be willing to provide that data. It would be nice to document that for historical purposes.
