shows a Fokker S-14 Mach trainer. Indeed a Post-war development. The worlds first dedicated jet training aircraft. Some 20 were built and operated by the RNethAF.
The Prototype, PH-XIV, c/n 6289 built in 1951 (S.14.1) is (unfortunately) stored at the Aviodrome museum in Lelystad, Holland. The L-11 is on display at the Militaire Luchtvaart Museum in Soesterberg, Holland.
Nurflügel Forever!
