There were far more Hurricanes than Spitfires during the Battle of Britain, but as can bee seen from these shots, the Spitfire evolved from the early eight machine gun aircraft in the second shot, that flew in the summer of 1940, to the bigger, heavier and almost twice as powerful cannon and heavy machine gun armed aircraft in the last shot. Although the Hurricane saw service right up until the end of the war with Far East squadrons, these aircraft were very much the same as those from the summer of 1940.
The Spitfire remained in production and in the front lines of Fighter Command from before the war right up to the end and beyond. No other allied type can make that claim.
I don't if there's any truth in that.
