Volume production of the "Airline" Sedan was planned for 1935 but the marque died with the Chairman, Sir Charles Kingsford Smith.
The first experimental Southern Cross was an open tourer with a body constructed by the Beale Piano works.
It was crafted from thin sheets of Queensland pine and walnut glued under pressure with aircraft casein glue.
This system, combined with the flexibility afforded by chassis-less construction, enabled the vehicle to be built without shock absorbers.
The open Tourer, which was christened by Lady Kingsford Smith at Mascot Aerodrome in 1933, was sold to a resident of Parramatta, NSW, in 1936.
