Arbeitsbuch to Katharina Grohsinger from Vienna. Second model issued in February 1940 by the Arbeitsamt Wien. After a few other jobs at the start of the war, she started working in the offices of the Flugmotorenwerke Ostmark in Wien-Mödling. This factory produced Daimler-Benz airplane motors, specifically the model Daimler-Benz DB 603, which was used in the Heinkel He 177 "Greif" bombers among others. She remained with the factory until the end of the war.  

The Arbeitsbuch is in complete and very good condition.
