Goodmorning Gents came upon this map on the weekend it is marked
ENGLAND SOUTH-ROYAL AIR FORCE EDITION-SHEET 11
FOR OFFICIAL USE ONLY
Three things drew me to this map ( 1 ) was the detail ( 2 ) was the color of the print ( 3 ) was the construction the back of the map is embedded with mesh to strenghten it which leads me to believe it was to be issued to Air crews. The map is so dated 1934 but I do believe it was carried over and used into the war years as there are amendments to the magnetic declination/variation dated from 1938 -1942 with the addition of Artillery,Mortar,AA,Bombing and Balloon fly zones I know on post war maps these areas would be labeled so that aviators knew were there safe fly zones were and what corridors they could use for safe flying I am assuming the same is so for this map or were these areas also active emplacements for the network of defence set up all over England during the war.
