Developed from the M-18, the first M20 prototype flew on February 26, 1928, and crashed on its initial flight killing the pilot Hans Hackmak. The second aircraft flew on August 3, 1928.
There were 3 models: a,b, and b2.
13 aircraft went to DLH and one to DVS. A number of crashes led Lufthansa to refuse to accept any more M20s, which resulted in the Messerschmitt company, Bayerische Flugzeugwerke (BFW) going bankrupt on 1 June 1931.
Eight survivors went to the Luftwaffe as trainers, the last one crashing in 1943. One was sold to Varig in Brazil in 1937 and flew on to 1948.
