YES droop snoot for the win! A Spit IX with additional rear-fuselage fuel would be fun too.
Anyway, Guppy, I've recently found out that Spitfire Mk.IX's, XIV's and XVI's had rear fuel tanks fitted to them beginning in 1945.
Dr.Price's book says that they had 75 Imp.Gal. fuel tanks while a cross section i found in a different book of a Spitfire F.Mk.IX (c-wing, merlin tail) had a 29 Imp.Gal. fuel tank. Any answers?
