I still have not worked out the drop in rank - unless it was a disciplinary matter ?? or perhaps loss of Flying Medical Category ?? (although it would seem harsh to bust him all the way down to AC2).
But if it was a discip matter he would then seem to have been commissioned on the very day he regained Temp Sgt (22/12/43) - which would also perhaps seem a little unlikely.
A bit of a puzzle.
