Brian. sad to say, passed on a few years ago. He had a lot of airfield research material, much of it WW1, and I encouraged his wife to donate it to the archive which she did, I understand. Brian was too much of a perfectionist to publish very much. He always thought that there was more to a story and kept on searching for the last pieces of the jigsaw that never seemed to be forthcoming. And yes, I loved that little Broadwell story too.
