'Pilot Lt G Stefanesco in the Nieuport Delage-NiD.72C1' during the 'Little Entente and Poland air rally'. Three examples of the French NiD.72 fighter were delivered to Belgium, four to Brazil and three, apparently, to Romania. Note construction number 1 - this would be the first production aircraft. C1 just stood for single-seat fighter. The Little Entente was a military alliance between Czechoslovakia, Romania and Yugoslavia. Photo from: Narodowe Archiwum Cyfrowe
