Ta very much
Thanks for that, Kermit and Who has control.
I have checked the website and there don't seem to be any for Kenley though I will order one of the Croydon ones. Incidentally, I wonder what the Luftwaffe's interest in some of these places was. For instance there are photos of Limpsfield...one wonders why they needed those unless there was a cricket match on at the time!!!!
