1910 Luger

[CharlieK]

I have a Luger that my wife's mother bought in the late 1970s from a woman who said that her late husband liberated it from a dead German officer in the First World War. Does anyone have any historical records from that era to confirm the officer's name or rank?

The serial numbers all match, including the magazine: 4099 On the front of the grip is this: 5.G.M.G.8.
