Only one Lysander, the first prototype, was converted with what was apparently called the Delanne wing - or tail - and the 4-gun turret. An extremely odd looking contraption with what looks like a much shortened fuselage and an extremely long span tail with twin fins. I've no idea about a pig to fly but it was said to be very stable in flight.
Westland P.12 in Google brings up many images.
I've never had any secret documents but I do have a book which says it covers all 653 (!) military airfields from WWII. I'm from Hertfordshire and now live in Derbyshire. The two counties together had only 10 airfields and I guess further west/north west would be similarly sparse which gives an idea of how crowded the southern and particularly eastern counties must have been.
