The clearest shot I ever got of this interesting exhibit at the Aviodrome. After WWII KLM boss Albert Plesman was quick to obtain a number of C-54s. Initially they operated as government aircraft, including wartime orange triangle military markings, until things normalised along the airline's route to the East Indies. This airframe is not the real NL-316 / PH-TCD, which was c/n 10312. Being repainted in KLM colours in 2019 to celebrate the airline's 100th anniversary.
Dutchman Frits Koolhoven designed this fighter for the British BAT company in 1918. F1654 was used for racing after the war, wearing these colours and provisional civil registration K-123. Beautifully restored, it was moved to the grand Rijksmuseum in Amsterdam in 2012, even though it's hardly a Dutch aircraft.
