Just spotted this.

Biddendenlocal, I have all of the OS Casini Grip 1940 War Edition maps for southern England.

I suspect your query is in relation to the crash site of Sgt Kean.

We do know the exact location. I can plot this for you and give you a current OS map ref for that site and the wartime reference. They are both quite different grid systems and numbering.
