The Spanish government ordered the first six Dornier Wal flying boats, built at Marina di Pisa in Italy, off the drawing board. In 1926 three of these made a return flight to Equatorial Guinea, including W-5 which was at that time named Cataluña. W-5 was written off after a landing accident at Melilla in 1929. A man seems to be riding in the engine bay forward of the radiator here. IWM could not identify this aircraft and the only link with Britain seem to be the Rolls-Roye Eagle engines.

Avia exhibition in The Hague. On the left is the Koolhoven stand with a mock-up of the FK.55 fighter and an FK.53, PH-FKJ. The Fokker D.XXI perching behind that is the first production aircraft, delivered to Finland as FR-76. The D.XXI prototype is painted on the wall. Photo from: Nationaal Archief (Netherlands)
