This early R III, registered in Sweden on 1 June 1922, was built by Walter Rieseler Kleinflugzeuge at Berlin - Johannisthal. The single-seat sport type was produced by Stahlwerk Mark in Breslau (now Wrocław) as the Stahlwerk Mark R.III/22 or Stahlwerk Mark Rieseler Sport. The name Rieseler is frequently misspelt as Riesler. Photo by: Oliver Lindkvist / Arlanda Flygsamlingar

The R III light single-seater, designed by brothers Werner and Walter Rieseler, was produced mainly in Breslau (now Wrocław) by the Stahlwerk Mark conglomerate, originally a steel mill. About 50 R III aircraft are thought to have been built. This photo was taken at Devau airport in Königsberg, East Prussia (now Kaliningrad) where the Altpreussen flying school was a Mark dealer.
