The flowers rule out Chipping Warden because Gordon was only there in the last half of January 45. There is a scattering of ranks from Pilot Officer to Wing Commander - the pilot with the Pathfinders Badge. Assuming that a DFC was given to the Captain after a tour, the Pathfinder has not got his yet! There are also a number of other awards that I have not identified.
Looking through the window - is that a wooded hill - does Silverstone have such a hill. I forgot to look when I was there 24/7/71!
Thank you for all your interesting comments
