You right about some things regarding the hurricane, most notably the armour protection for the pilot and also the guns it carried.

Im sure that in game the model is a MkIIa (series 2) which would mean it has a longer propeller spinner, it was first built in october 1940 under the MkIIa series 2 but in april 1941 it was named the MkIIb

the MkIIb generally had a top speed of around 300MPH, lowering its speed from the MkI due to it being fitted with racks to carry bombs/drop tanks, most notably 2x 250lb or 2x 500lb bombs.
