Welcome and this might help ...
Try our Google CSE (Custom Search Engine) which is located at the top right corner of the forums, just under the standard search box. It's a piece of custom code from Google that just searches Milsurps.Com posts and threads, including the archive.
I typed in the phrase reference book m1 carbine and got a ton of hits from older posts. Try various other phrases and I think you'll find a lot of good information you're looking for.
Regards,
Doug
