Have this Luger with 1918 holster and a non matching magazine plus a spare fxo late WWII magazine. It has a strange lever holding a side plate on. Numbers on Luger all match... What do I have? Was it issued in both wars? It came to the US via my great Uncle who was in the Army as a SGT with the 366 Field Hospital in Europe. Did not get a story about it from him as he drank himself to death and passed in 1964.
