We're not looking at a Wicko/Warferry.
The challenge aircraft was the third built by the extraordianry Geoffrey Wickner (I have found no reference at all to the first)
It was a development of this little beauty (80Hp Anzani) with the wing position moved and a Cirrus engine fitted.
Wickner was a cousin of Edgar Percival, himself an Ozmate whose middle name was - guess what? Wickner! Wickner worked with Percival for some time in the war years I believe.
He died in 1990
The challenge aircraft was the third built by the extraordianry Capt. Wickner
(I have found no detail whatsoever on the first)
(Uh-oh! It seems Wickner was far more prolific that that! Probably two designs, one of them spectacularly successful, preceeded the one below, plus a series of gliders!)
