This engine was installed in a RAAF deHavilland DH9A A1-20. It was recovered from the rubbish tip at old Wave Hill Station.
The aircraft was flown to Wave Hill Station by Sgt Pilot Eric Douglas in a flight commanded by Charles Eton in 1929 during the “Coffee Royal” affair and the search for Charles Kingsford-Smith. The plane caught fire, was damaged and abandoned.
The massive propeller for this aircraft is in the mess hall at Wave Hill Station.
