Manufactured by Netzschkauer Maschinenfabrik of Netzschkau in Saxony, 1923-1925.
This was a two-seater tricycle with front wheel steering. The air-cooled 200cc 2-stroke engine was mounted at the rear driving the axle via chain. Claimed performance was 50 km/h.
In 1945 the company was taken by the Russians and the owners, brothers Franz and Gottwald Stark, were imprisoned in Buchenwald Special Camp No. 2, where they were killed. The Russians seem to have learned much from the Nazis.
