I have a 9mm German Luger with serial number 2988 and the 88 is displayed on many other parts of the gun as well. It has an Eagle proof marking sitting on a ball and there is an "L" next to the Eagle. I'm very new to this and was hoping someone could tell me a little something about this gun. It does not have a matching magazine. My overall objective here is to see if somehow I could track down and purchase a 2988 magazine? Where are the best places to try to look to find a magazine like that?
