Received a message from a very knowledgeable person: "Your luger belonged to the 328 Landwehr-Infanterie-Regiment that was part of the 25 th Landwehr Division and battled on the Chemin des Dames on the Western Front during WWI. "
That comes as a shock to me: my very own grandfather, Ernest Lacoue-Labarthe, was in the Argonne and in Verdun. He and his unit were engaged in the bloody fights over the "Chemin des Dames", where he sustained a minor wound to his knee from a grenade shrapnel. After all these years and distance, knowing this pistol I just bought could have been the sidearm of one of the officers from the units facing my grand father is, to say the least, rather troubling!
