I have a 3.29 million Garand built at the tail end of 1944. I know -12 bolts were put in some of the late 1944 Garands. What were the last heat lot numbers for the -12 bolts or where can I find it/ kwg

SA-1 or 011A

I think S-A2, as seen in 4 or 5 different 3/44- 2/45 rifles, S-A3 as seen in about 2 or 3 different 5/44-8/44. S-04 reported by a friend in a 12/44 rifle.
Maybe a RE6B , as seen in 2 different 10/44 rifles
(seen means-seen by me, in what I think are original-ish rifles)
011A --is one I have never seen! (in a -12 bolt) . in a -18 bolt I have 011B,
When is this gonna end????
