'Aviator Clarence Chamberlin's plane'. Built as an L-8A Sirius in 1930. Sold to 'Dutch' Shankle and also flown by his wife, air racer Joan Fay. Converted to L-8D Altair in 1932. Sold to Louise Ashby, Chamberlin's wife, in May 1936. The Chamberlins intended to make a stratospheric transatlantic honeymoon flight for which the razorback canopy was added after August 1936. It did not happen and the aircraft was sold to the US Army Engineers Office through broker Charles Babb in 1940. The Curtiss 53 Condor in the background was also owned by Chamberlin or his wife.

Owned by famed aviator Charles Kingsford Smith, VH-USB left Australia by air in October 1934 for the US. In September 1935 it was shipped on to the UK where it became G-ADUS for an attempt on the UK-Australia record. It crashed into the Gulf of Martaban, Myanmar, on November 8, 1935. An undercarriage leg washed up on Aye island but otherwise no traces of the -USB, Smithy and copilot Tommy Pethybridge were ever found.
