Just a little bit of info on Mk.XII
Type 366-Mk XII
The first major change to the Spitfire was the introduction of the Griffon engine. Like the Merlin it was a V12 supercharged engine, of 36 litres swept volume rather than the 27 liters of the Merlin. The 4-bladed airscrew also turned the opposite way. The Griffon III or IV fitted to the Mk XII generated around 1720 HP. 100 were produced. A retractable tailwheel appeared early in the production run, and most were clipped-wing, low altitude variants.

And just a minor detail, XII had (at least on all pics I saw) asymetrical radiators like Spit V.
