Hawker Hurricane,Battle of Britain 1940.
During the Battle of Britain fighter markings underwent a complete revision in June 1940.The black & grey undersurfaces were abandoned and replaced by a single colour which was officially described as duck egg blue,the actual colour is best described as a very pale greenish shade which did vary depending on paint manufacturer and squadron practises ( ie pouring different colours into a single tin to use up valuable paint supplies !) the pre war practise of painting the rudder stripes onto the rudder were abandoned in favour being placed onto the tail fin,this avoided any problems with the balance of the moving control surface.
