Hi I would love to be able to help having something of an interest in Court Line myself However the photography is not mine to grant you any rights to as you point out one of them is airline publicity material and the other is of unknown origin it may be in the public domain but I wouldn t know for sure You can obtain many photographs of Court Line aircraft from airliners net do a freeform search for court line it should throw up fifty or so images You will probably have more luck contacting the individual photographers through that site since all the images are usually attributed to someone It s also worth digging out the book colours in the sky which is a detailed history of Court try an Amazon search in the first instance again contacting the authors would be the way to go since I believe they have amassed a large amount of photographic material and ephemera from the airline Good luck
