Achim-
Ray Brooks was a friend of mine. Let me see what I can do. I have several notes from Ray written on personal notecards with a watercolor of Ray on the cover. Let me know if you are interested and I can scan the painting for you.
Ray's collection is held at the National Air and Space Museum and they can also provide photographs on request if I do not have anything.
