Many Thanks Bill for your comments - This may well indeed be a case of being promoted after his death?.
I know & have Pictures of him as a WO2 around the time he went missing in early June 1944 - I suspect that his Pilot Officer Rank may well have come Posthumously after the Official Gazzette Statement/s of MIA in October 1944 and finally KIA in May 1945.
Hopefully when I finally receive his Records from Canada it may be well be proof that this was so?
