Jeff West was the New Zealander who was Bader’s wingman that day. When Dilp Sarkar first brought up the “Friendly Fire” theory, he initially stated that he was not publishing any names in “Bader’s Tangmere Spitfires” for “ethical” reasons. From a short telephone conversation I had with Johnnie Johnson in 1997, I suspect he had some hand in this – he was adamant that neither Buck Casson or Jeff West would have been involved but he also admitted he had unswerving loyalties to all three. It seems unfortunate and perhaps suspicious that all these theories get aired once the participants have gone.

There is a Spanish Civil War rendition of the Airspeed Viceroy on this page http://www.zi.ku.dk/personal/drnash/model/spain/did.html
I know this is an old thread but I picked up on it after finding that my father put the Viceroy through its C of A at Martlesham October 6-8 1934 in order for it to compete in the McRobertson race on October 20. You might pick up a colour scheme from material about the race. (I’m trying to find the full names and history of the pilots -N.Stack and S.L.Turner).
Cheers – if you completed the model I’d love a pic!
