Seeing that great shot of MK923 in the museum, that under surface 'blue' still offends.
I had prepared all the painting details/spec for Bill Ross when he undertook major refurbishment of MK923 for Cliff Robertson in the mid 1970's - works paint drawings, colour chips and templates for the codes. I researched at our then public Record Office and established that MK923 was aircraft Z of 5J/126 Squadron RAF. So we could get it exactly as it was when operational from May to December 1944.
When it came to application Jerry Billing assured Bill that I was wrong, it was not 'Medium Sea Grey', as I had directed, but a duck egg blue.
Good old Jerry, too much time in the Mediterranean sun in Malta flying Med theatre Spitfires with 'Azure Blue' undersides.
At this time I was working for GM/Vauxhall here in the UK and I was mightily impressed to be tracked down by phone during my daily travels within the company (no mobiles back then) to receive a call from Cliff in the US to thank me. Subsequently I too, like Bill Greenwood, met him at the Carefree private function. My wife is a big fan and I noted how he worked the hanger gently, talking to every group in the course of an hour or so. You don't have to do that - a gentleman.
It is my understanding talking to both Jerry Billing and Gordon Plaskett, who had coached him in the TF-51, that although the longest private owner of a Spitfire airworthy or otherwise he had never flown it.
