help identifying my new luger

[tblazerss]

ok sorry I just put the pics in the attachment a am hoping I got it right. I can program a metric motorcycle computer but have a heck of a time doing these types of things on a compluter. The mag to the pistol is aluminum #37 with a fxo over it on the bottom a #37 on top of the mag and there is the german proof mark over each of the #37's. Let me know what you all think when you see the pics. Please I hope I did all this and you can see em.
