Nearly right but, you can have the points, The photo was taken at RAF Fiskerton, 49th Sqd. 1943 but within a few weeks of it being taken, a few of them, including my father the tall one, were transferred to the new 617 Sqd. Scampton.
Dad worked at Rhos County garage, joined the RAF in 39 as a mechanic his plane was M-mother, I am still researching his history, he never talked a lot about those days.
Well done, I was joking when I said now for part two of the question, but you "did good"
