Just got a few Garands

[Hawkes54]

Hello everyone, I just bought two Springfield Armory M1 Garands made late 43 early 44 and had a few questions on some of the markings that they had. One M1 is in great shape while the other has seen better days. The first three pictures are the same M1 that's in good shape while the last is the worse of the two. If anyone knows anything about the markings that I posted pictures of I'd like to know. Thanks!

Those are rack numbers, made it easier inventorying and keeping track of rifles than looking at serial numbers

Please post more photos. Need barrel, bolt, trigger housing and op rod photos.
