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.
