* 1908 DWM, s/n 7089a : 131.R.6.3. - signifies 131 Infanterie-Regiment, 6 Kompagnie, Waffe Nr. 3
The 131 Regiment was part of the 42nd Division during World War I. It battled in Lorraine and on the Somme during 1914. In 1915 the Division was transferred to the Eastern Front to battle at Mariampol, Vilna, Lake Narotch, Galicia, Riga, and Oesel Island. In late 1917 the Division returned to France and battled on the Western Front for the remainder of the War. (Histories of 251 Divisions of the German Army that participated in the War, 1914-1918)
Observations indicates that 1908 First Issue Lugers magazines have the large numbers that align along the long axis of the magazine. The magazine with the Luger could be an arsenal replacement or a later replacement by a collector or even Waffenfabrik USA.
