One question for you – many sources say the RFTS Spits were all
XVIe versions (“e” for clipped wing) but in the film and all stills I’ve
seen they all have the classic curved wing. Sorry I’m not that
knowledgable on the Spitfire but did the “e” have clipped and
elliptical wings?

I thought the “A” “B” “C” and “e” designations were to do with the configuration of the guns fitted or that could be fitted ?
