The Polish 303rd RAF Squadron had the highest number of kills of any RAF Squadron, and they flew Hurricanes.
True, but the large number of still flying Spitfires must be due to their all metal construction.
I remember in the 60’s every old WWII airfield site had a Spitfire on display as a ‘gate guard’. I think in the 80’s someone had the bright idea of rescuing these gate guards and restoring them. They were replaced by fiberglass replicas, greatly increasing the number of airworthy Spitfires.
The wooden wings and fabric covering of the Hurricanes just couldn't stand the UK elements as gate guards, so while they had more kills, they just didn't remain around after WWII.
I personally have a good remembrance of the Spitfire (and Mosquito) watching them as a kid flying over our house at the end of meteorological flights going into Speke Airport from RAF Woodvale.
