That looks to be a version of the wartime Dutch Fokker D.XXIII fighter.
The prototype as flown used Walter Sagitta air-cooled In-line engines, although the plan was to offer customers various more powerful engine types,
including Rolls-Royce Kestrel XV, Rolls-Royce Merlin II, Hispano-Suiza 12Xcr, Junkers Jumo 210G, Isotta-Frascini Delta RC 35 ID and Gnome-Rhone 14M4 radials.
