Some success Finally,
I have jumped through many, many hoops and was lucky enough to get from the royal household copies of Prince Philips logbook from when he flew my chipmunk WP861 and also the RAF museum WP912,
Unfortunately I cant share them on this forum as I am under strict instruction no to post them in any public places ad understandably they are his private property.
I am writing to the duke so never know what may come from it!,
