Stock and recoil plate screw question.

[Gus Fisher]

Folks,

I'm going through a bunch of carbines for a few friends and I've run across a couple things I don't know. Any help would be very much appreciated.

First, one high wood stock has the initials S and A on the forward top left side. Is this a replacement/rebuild stock?

Also and this is getting really nit picky, one of the recoil plate screws is threaded all the way up to within about 1/4 inch of the head. Never saw one threaded that far up before. The top outside edge of the screw edge also seems slightly rounded. This came on a CMP carbine. Is this early, unusual, or just "another way they did it?"

Thanks a bunch

The stock is a replacement made by Springfield Armory.

The fully threaded recoil plate screw was made by one specific manufacturer during WWII. All of the other manufacturers made the partialy threaded screws.

Thanks for the info, Brian.
