Sportflugzeugbau Rieseler

Germany
Established at Berlin/Johannisthal Aerodrome after First World War, Sportflugzeugbau Rieseler built a single-engine single-seat light sporting parasol monoplane with a two cylinder Haacke engine which was put into production by Stahlwerk Mark at Breslau. A two-seat version, the R.IV/23, was subsequently developed.
