Hello, I just found a type 2 mauser magazine with r suffix. It has the stick E63. Could this have been issued with an r suffix 1937 s/42 luger. Luger has droop E63. I am trying to find a mag that is close to matching my pistol. Thanks for your help. P.S. I have learned more about lugers from this forum and Jans books than I ever imagined possible. John
