Hello,
the same question about RN/CC grid system.
I read the following thread
http://www.rafcommands.com/forum/sho...tude-positions
so I understand the principle. But maybe relevant documents/maps have become available since then?
Many quadrates are interesting, for example:
RNXU3510 14.May.41
DPQJ1728 1.Jun.41
Best regards,
Andrey
