I don't think so. Most Super Grade pre-war rifles came with
the pre-war safety.

I think that the big W got the hint and revamped the safety.

You can Google image pre-war transition safety to see what it looked like.

The second change to the safety is pretty much what we have today.

Winchester did use some of the pre-war safeties and shrouds on transition
guns to utilize the parts.
