Thanks.  Caught it at Temora Warbirds Downunder a couple of years ago. The sound she makes is incredible.

Turn you speakers up when listening to this video: www.youtube.com/watch?v=p5RNoR…
The engine is a Pratt & Whitney Wasp, the same engien as used in the C-47 Transport aircraft.

Wow!!
I quickly looked up the Boomerang in Jane's WWII Aircraft and it seems it did pretty well. No wonder with that engine! I've often heard it on the Dak. I must say, there's just something about a radial engine.
(Interesting to hear the whine of the airframe as it goes into the turn!)

Yeah it was the wind rushing across the gun ports that makes the unique whistle.
