NICE CONDITION OF ORIGIN. The Junkers Ju 52/3m (nicknamed Tante Ju and Iron Annie) is a German trimotor transport aircraft manufactured from 1931 to 1952. Initially designed with a single engine but subsequently produced as a trimotor, it saw both civilian and military service during the 1930s and 1940s. In a civilian role, it flew with over twelve air carriers including Swissair and Deutsche Luft Hansa as an airliner and freight hauler. In a military role, it flew with the Luftwaffe as a troop and cargo transport and briefly as a medium bomber. The Ju 52 continued in postwar service with military and civilian air fleets well into the 1980s. The Ju 52 was similar to the company's previous Junkers W 33, although larger. In 1930, Ernst Zindel and his team designed the Ju 52 at the Junkers works at Dessau. The aircraft's unusual corrugated duralumin metal skin, pioneered by Junkers during World War I, strengthened the whole structure.
