I'm just wondering about the SG markings on these mag catches. two of them have the SG stamped closer together than the other. The rails on all three measure between .095 and .098. Then I have a type 3 ( thin .070 rail ) marked E-S G with an M on the face. Riesch's book doesn't show a E-S G type 3 mag catch. I know that this doesn't mean that it doesn't exist. I would just like to get some opinions.
Thanks, Greg V
