I recently came into possession of a 1913 Erfurt Luger, serial number 3196. I have done some research but I am still unsure of what I have. Any help in identifing or value would be appreciated.

Hey, just acquired an Erfurt 1918 P-08. I'm a Luger novice and am not familiar with the markings. Are they unit markings? I can post photos if someone can assist. Would love to know where it wouldve been in WW1. Thanks!
