A'rtnoon Graeme,
Well, you've found my image, but stricktly speaking you're only half right now!
although the challenge aircraft is not in Wiki, its successor is and has this "half" bit!!
If you read that article, it shows the T-2 as a line drawing (on the left) and the Photo actually shows the
ACAZ T-1
I'd be a hard man to deny you though mate, so

Sorry Mel, maybe I should have done a "Morten" on him and rejected the answer
