Long Range Spitfire

Today this piece of art represents an aircraft I have never seen in the flesh, I have just read about them and seen photos and drawings of them.

The aircraft shown is a Spitfire Mk II LR P8448 UM-D of 152 Squadron in 1941 escorting some Blenheim bombers on a raid into Germany. About 60 Mk II spitfires were converted with a 40 gallon fuel tank under the port wing to allow them to perform long range escort duties.
