1. You refer to a position given by an AA Searchlight Bty stationed at South Benfleet in 1940 and I attach part of a map indicating that the 'M' relates to the 'M' Square.
2. Referring to Sheet 108 (extract attached), your coordinates 184 and 093 of your 6 figure reference refer to the 18 09 square and the 3rd figure '4' and 6th figure '3' refer to the tenths in the 18 09 square.
I have marked the square with a blue arrow and approximated the tenths and pencilled in a cross.
Try also Andy Saunders on this forum.
I hope you can trace further information and possibly some accounts of the crash.
Regards Mark
