Dear All,
I have come across a grid location of MBRU 3452. It was in use in Apr 1940. It was probably UK Navy. It was probably between Leuchars and Norway/Denmark/Germany. None of the on-line Grid Converters I've found are very happy with an input of 4 x letters, then 4 x numbers - in fact they positively dislike them!
I am obviously doing something wrong - but what? I've never seen a grid location in that format - might it be a typo? If it's not, then where is it?
Conversion to Lat/Lon needed to tie up the loose end of where one of my "Local Lads" was last known to be.
TIA
Peter Davies
