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
