Hello, this stamp tonight from the Netherland Indies. From a set of 5 stamps issued in 1928 just a few years the aircraft, a Fokker F.VIIa, went into service I believe.
This was a single-engined transport aircraft, slightly larger than F.VII with new undercarriage and wing. First flown on 12 March 1925. The first aircraft had 420 hp (310 kW) V-12 Packard Liberty engines but the remaining 39 F.VIIa had mostly radial Bristol Jupiter or Pratt Whitney Wasp engines. The aircraft was also known as a Fokker Trimotor.
Some famous aviators flew this aircraft or a variant of it, including Sir Charles Kingsford Smith in his F.VIIb/3m Southern Cross which was the first aircraft to cross the Pacific from the United States to Australia in June 1928, and the first to cross the Tasman Sea, flying from Australia to New Zealand and back in September of that year.
Have a great weekend……… Michael
