As it now appears to be Brian Abrahams challenge, could I start the ball rolling by suggesting a Ryan FR-1 Fireball?

Southern hemisphere mustpost.

Aha - thank you. Checked the list, and it hasn't been done so - CAC Wirraway?

Hmmm. I was thinking along similar lines but unable to confirm. Wackett?

I show the CAC Wirraway being posted in WC Mk.I #47.

The CAC CA-15 'Kangaroo' ?

I will "fill in" with CAC-12, 13, 14, 19 Boomerang, to complete the set. Keith.

I may be wrong, but the cockpit combing shape fairly screams 'North American'. I initially thought a CAC built Mustang, and then perhaps the CAC Wirraway, but the cockpit instruments seem too complex for the Wirraway, and as stated earlier, it has been posted previously. The rather massive crank on the starboard side of the cockpit bespeaks of a substantial machine. The word PROTOTYPE appears to be etched on a placard as well, which leads me to believe it is the one-off CAC-15. I do know one thing for sure,..it is not a Wackett.:)

Sorry for the late response but the Command insists on other tasks be done from time to time. CA-15 it is. Is there nothing you people don't know? Looks like you win evansb.

Thanks Brian! A great challenge for a great aircraft! I have read that the CA-15 Kangaroo was a superb performer. Here is a rare photo of another rare aircraft. This is the only cockpit photo of the mystery aircraft that I know of.

The mystery aircraft did enter serial production, but no examples are extant.

Bri
No takers yet, looking at the compass and instruments am I correct in saying this aircraft was a British aircraft possibly late WW1?
Mel

Hello Mel! Yes on both accounts. After the war a few entered civilian hands.

Please allow me to be the first to get it so wrong (as usual) haha. Keith.
SOPWITH CUCKOO ????

DH 9 ? Seeing as some became early airliners.

Possibly the Bristol M.1.C, some of these aircraft did fly as civilian aircraft. However, there is a replica in the Shuttleworth Collection which doesn't tie in with your earlier statement regarding no extant versions.

Not a Sopwith Cuckoo, (love the name), a De Havilland DH 9, nor a Bristol. The type had an interesting, albeit short, history. The last one was scrapped in the late 1920s.

Not the Gugnunc, I suppose?

Sorry stevef, not the Handley Page HP.39 Gugnunc. The mystery aircraft did service in World War One.

Ok same family, different model, SOPWITH SALAMANDER ????? Keith ???
