The one and only Boeing 226 was a luxury corporate version of the Boeing 80A airliner. Initially fitted with ring cowlings and wheel spats, these were discarded in service. NC233M was cancelled from the register in October 1937. Photo from: City of Vancouver Archives

Stanavo was the aviation fuel brand of Standard Oil (Esso). This airframe was originally Vega 5 NC7440, c/n 20. It was rebuilt in September-October 1929 and the new c/n 118 was issued. 'Originally painted white, red lettering, then with eagle outline and later with full length eagle paint job, red on white.' When Jimmie Mattern acquired it in 1933 it was presumably in a dismantled state. It was refurbished using only a few parts of his crashed Vega NR869E (c/n 69), but Mattern wished to retain his old reg. He crashed the new NR869E in Siberia in June 1933.
