Yes I have, and the same for service dress tunics, although as you know, any RAAF battledress is rare. Sounds like a lovely example.
I have a 1944 dated RAAF nav BD. It belonged to a bloke named Cooper and was given to me by his widow. I met her during research for my forthcoming book on 617 Sqn, as she had been childhood friends and then the fiancee of Gibsons bomb Aimer, Fred Spafford. After he was confirmed killed, she met and married Cooper and hearing of my collecting interest had someone send it over to me.
I know Dave Shannon used an RAF BD, with titles, but I am pretty sure with Aussie made wings. I'll dig out my photos and if they turn out to be Brit, I'll post a photo.
