Well done Moze! 🙂
You have control…

Yes Eric, it is the Richardson monoplane. The engine was initially designed by Archibold Richardson, who was joined by his brother Mervyn Victor. To manufacture the engine, Harold “Curly” Eagle came on board and later a fourth partner, Ted Sparks. Construction of both the engine and airframe was completed by 1916 and given the name “Swift”. Taxi trials were carried out by Capt Billy Stutt at Ham Common (which later became Richmond AFB) in June 1917 and he recommended modification to overcome tail heaviness. Further delays to testing made Archibold impatient and during a high speed taxi, unintentionally became airborne and crashed. The engine was packed away in boxes and the airframe hung up in the roof of the workshop where it had been built. The airframe survived until 1935 before being burned.
Archibold died during WWII and his brother Mervyn went on to invent the Victa lawnmower in 1953.
“Curly’s” son Norman decided to restore the unique engine in 1974 and had it running by 1984. It was subsequently donated to the Powerhouse Museum in Sydney in 1993.
Over to you Eric!

Time for some more clues.
This Wot, including its engine, was designed and built by a group of four fellows in Sydney between 1913 and 1917. The engine is a six cylinder rotary, with counter rotating propellers.

Australian banknotes have featured aviation themes over the years, for example, Sir Charles Kingsford Smith (famous pilot) and Lawrence Hargrave (aeronautical pioneer) on the old paper $20 note:

On the currrent polymer notes, we have Rev John Flynn (founder of the Flying Doctor Service) on the $20 note:

and David Unaipon (inventor) on the $50 note:

That would be the Gloster Gamecock reproduction at the Jet Age Museum. 🙂

Excellent post Peter!

Nice try RAB, but this one was in March 1917.
