Hi Ian I know that this is a few years on, but my Granddad was also in the MNBDO. He was also captured in Crete in May 1941 during the rear guard action, I think he was sent to STALAG Luff 8b prison of war camp. I have several photos the main one being of the whole unit at before they left. His name was William Mitchell most probably nicknamed Bill Mitchell he was from Cornwall. Regards Derek PS I was also in the Air Force from 1989 to 2013 I was posted to Brawdy, Brize, Lyneham, Marham and Boscombe Down.
