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
