Awesome drawing!
One nit-pick though. I believe that omega became the symbol of 892 Squadron FAA only after the decision to scrap aircraft carriers has been made and the unit was to be the last (as it seemed back then) fighter squadron of the RN. So Having it on P.1154, while not impossible, seems bit unlikely, because continuation of this program would imply that there still
are and will be aircraft carriers (rather more than one) in the RN and therefore 892nd isn't
the last.
