Airfield Charts

Spooky, I was thinking the same. I liked the ones in After the Battle Then and Now books, they are dated 1951 and show most disused airfields.
I have a RAF set from TNA dated 1946 but they exclude a number of airfields that were either closed or not RAF, e.g. St Davids and Carew Cheriton.
There must be charts from the 1960's and 1970's as well.
There have been a number of charts on eBay but without knowing what they look like I have steered clear. As a result of Peaceful Fields and norwichpauls pre-war audit I was tempted to draw up a 1933 map or 1929 -1939. Trouble is what base map to use.
