Arbeitsbuch - Junkers and BMW factory employee 1939-45

2nd edition Arbeitsbuch issued to Michael Kremer (not 100% sure of his first name). Born in Graz, Austria, in August 1914, he appears to have completed an apprenticeship / training in 1932. The entries and stamps indicate that he started working for the Junkers aviation company in mid-August 1939, continuing to work at the large Junkers factory in Dessau until March 1943. From March 43 to June 45 he worked for BMW (Bayerische Motoren Werke) at a factory in Munich, constructing motors. He was employed as an “aircraft parts manufacturer” (Teilkonstrukteur im Flugzeugbau). The entries go on to state the he worked in the tele-communications field after the war (they trace his employment until 1946). Interesting Arbeitsbuch for someone who worked in the wartime aviation industry throughout the war. A 1939 regulations leaflet has been glued into the Arbeitsbuch.
