Hello Old Duffer
My father (still with us age 95) was at RAF Padgate in 1946, he arrived there in 0ctober 1945 and departed on the 17th May1946 travelling to Tilbury docks to board the Strathaird. He served in India and Singapore on motor transport duties.
Padgate was a big camp where hundreds trained so the likelihood of Dad being in your picture is unlikely but a possibility, if I send you a PM with my address could you post the picture to me.
