I’ll just quote Airfix’s description:
“Considered revolutionary when it was unveiled in 1935, by the start of WWII the earliest versions with fabric covered wings and two bladed propellers had fallen behind the performance of the best German fighters. Nevertheless, once fitted with 3-blade propellers these early Hurricanes were very successful during the Battle of Britain in 1940.” 
I must have seen the real plane bearing these markings many times – it is in the Science Museum, London .
