Based on the successful Mü 13 "Atalante", the Mü 13 D1 variant was produced from 1939 onwards by the company Schwarzwald Flugzeugbau Wilhelm Jehle in Donaueschingen. The Mü 13 D1 was further developed into a variant Mü 13 D3 with an extended fuselage and larger rudder, which was first built in 1942. A total of 150 of the three types were produced
by the end of the war. In 1942, glider production was practically halted on the orders of the main client, the Reich Air Ministry. Only in 1943 did glider production briefly resurface when three prototypes of the "Strolch" type – a further development of the over 20-year-old type?

According to this report, the factory was already producing gliders in the 1930s (the Mü 13 and the Göppingen 1, Wolf, under license).
The NSFK was a good customer. As part of securing the "fighter program," standard command units for gasoline aircraft engines, control units
for all special engines [the new jet engine], and control units for special purposes were produced.
The author Sturm continues: Soon, alongside the Ju 322 "Mammut," the giant (Me 321
and Me 323), equipped with tail unit parts (elevator) from Schwarzwald Flugzeugbau Donaueschingen, were flying in Russia or Africa. Schwarzwald Flugzeugbau manufactured 200 tail units for the Me 321 in 1941 (according to another source, 290), and at least 75 elevators for the Me 8-323 in 1942. In addition, the factory manufactured another 2,249 wooden tail units in 1943 and 1944 for unknown aircraft types, probably mainly the Bf 109.
