BMW
After the end of World War I in 1918, BMW was forced to cease aircraft engine production by the terms of the Versailles Armistice Treaty. To remain in business, BMW produced farm equipment, household items and railway brakes. In 1922, former major shareholder Camillo Castiglioni purchased the rights to the name BMW, which led to the company descended from Rapp Motorenwerke being renamed Süddeutsche Bremse AG (known today as Knorr-Bremse). Castiglioni was also an investor in another aircraft company, called "Bayerische Flugzeugwerke", which he renamed BMW.The disused factory of Bayerische Flugzeugwerke was re-opened to produce engines for buses, trucks, farm equipment and pumps, under the brand name BMW. BMW's corporate history considers the founding date of Bayerische Flugzeugwerke (7 March 1916) to be the birth of the company.
BMW 327
During the 1930s, Eisenach was the centre of BMW’s automobile manufacturing. In 1945, Eisenach was occupied by United States forces. However, the wartime allies had already agreed that Thuringia would fall within the Soviet occupation zone. BMW's automobile factory in Eisenach was not fully destroyed, and assembly of the 327 resumed. Clear production figures are hard to obtain, but many of the 327s surviving with collectors into the twenty-first century were post-war products. After the war, it became clear that the Soviets would not return the Eisenach factory to BMW. BMW-branded automobiles produced between 1946 and 1951 were therefore being produced outside the control of BMW headquarters in Munich. This caused a protracted dispute concerning title to the BMW brand and other assets, but in 1952 it was determined that Eisenach-produced models such as the 327s should be badged as EMW (Eisenacher Motoren Werke) rather than as BMW (Bayerische Motoren Werke). EMW changed their badge from BMW's blue and white roundel to a red and white roundel.
