It is a thorny issue!
I concede that I don't have any cc'd copies, or carbons (as was the way back then), and it is possible Ken supplied photo-copies of his photo-copies, and as I put the crux info from them in Leap', I put it in the public domain, and to be honest, there's no point writing a book about something if you don't want it refered to!!
As for Brooklands, different matter altogether. Mrs Gardner gave me a print, and the neg' of a picture her husband, Goldie had taken (he was Sir Malcolm's project manager) of the 1933 Blue Bird being shaken down at Brooklands, along with a letter confirming transfer of copyright (which stays in place for 60 years after the death of the originator).
Then the picture appears on the Brooklands website, and is going into a new book. When I pointed out they need to ask me their response was? " well you can see it's Brooklands in the background so it must be our copyright" !!!! I then pointed out that their "copy" is obviously a scan, you can even see the staples from where it's been scanned from Leap' (the original obviously has no staples being a proper print), the response? "but it was taken at Brooklands, it must be ours". Er? NO!!
