Achtng, Indianer!! 

That's interesting about the Spitifire and 109 dogfight but I dont think that the Spitfire and Hurricanes could dive like the Messers. and I will find quotes to show you that... I spoke with a pilot that Fought with The Corpo Aereo Italiano (tenente Giulio Cesare Giuntella) and Adolf Galland had told them to dive vertically ( a thing  that both Fiat planes - and the 109 -  could do but not the Spitfire...) if a British fighter got on their tail, even if the italian pilots preferred to perform out-roll and out turn the british monoplanes to shot at them when out of the maneuvre...
Saluti da ROma!!!
