This Soldbuch and militärpaß belonged to the same soldier. His last name is Wossner. As we look through his militärpaß, we see that he was born in 1896 and that he was a native of Württemberg. We can tell that he passed through the 3rd Recruit Depot with Infantry Regiment Nr 125 in October 1915. He was immediately reassigned to Flieger-Ersatz-Abteilung Nr 10 near Stuttgart. Entries continue from his November reassignment through December 1916 with him attached to Flugpark 5 (a training depot and point of distribution of aviation personnel to front line squadrons.). We then see notations for Flieger-Abteilung (A) Nr 211 which is dated 21 November 1918 so he obviously survived the war. There are also unit stampings for FA 201 and 210 from the period of 1917-1918. In his Soldbuch we see entries for FA 202, 207, and210 along with his service in these units. A well traveled ground crewman by any means. It is unusual to be able to offer both the militärpaß and the Soldbuch together.
