I don't have anything to use these for and wanted to sell but just don't know what they are worth.

The OM mag was made by Olin Matheson the company that owned Winchester at the time. The BRW S-I mag is it marked "S-1" or 'S-I"? S-I is correct for a USGI mag. There are a lot of fake mags out there especially BRW's. OM mags have been faked too. By the way BRW's were made by Borg Warner and the most common. If you could post or send me photos of the spines of the mags and markings I can verify if they are USGI or not.  Both mags should have five dimples on the mag latch. On the BRW the center dimple should be towards the top slightly and on the OM mag the center dimple should be towards the bottom. On the front of each mag there should be 13 spot welds. 12 in a row up the center and the 13th off to the right of the hole on the front. Also sometimes the mag follwers on BRW and OM mags are stamped BW for BRW and OM for OM. Although mags have been rebuilt over the years and they are not always marked. You would hav eto take them apart to check. Guys in states with hicap mag bans can't buy newly made 20 rounds mags so they look for preban mags. If legit they will be easy to sell. The other two mags should be Atwood Vacuum and not as common. The M with a slash is actually a stylized AV. I can't remember off the top of my head how many dimples on the latch plate but i think it's five as well. The spot weld pattern on the front should be the same as the others. Hope this helps. If they all check out as USGI then value will be based upon condition. Feel free to PM or email if you have questions. Pics would help though.

Are you referring to the magazines for the M-1 Carbine or something else?

What you have are 4 USGI M-14 magazines, which can be identified by the spot welds up the front.  You have one Olin Mathison(Winchester), one Borg Warner, and 2 Atwood Vcuum Machine. Stylized "AVM".
