Discrition of photo from Kees Kort,
Civil flying during the interwar years. The picture gives a view of a flying show with two Pander biplanes - actually sesquiplanes - on the ground. Flying over is a Fokker D.VII then in use with the LA (Luchtvaart Afdeling) of the Dutch army. The civil biplane seen fully on the ground is a Pander EF. As this type was further differentiated by the strength of the engine, it was either an EF 85 (85 hp engine) or an EF 80 (80 hp engine) The civil registration cannot be fully seen, but it could be either the PF-AFJ (c/n.30), the PF-AFZ (c/n. 31) or rhwe PH-AFX (c/n.38).
