ive never seen anyone deffinitively prove when and how many spitfire quadrons were operational with 100 octane fuel. sure it was there and used but when was it first introduced and how many squadrons used it?
further, the brits weren't the only ones with better fuel. 109s and 110s both were using C3 about halfway through as well. anything with a /N suffix was using C3 and 2700RPMs for 5 minute WEP.
oh and the spitfires didnt have variable flaps.
