Hi all,

I would like to ask for the exact position of the "Datum Point" used in the Coastal Command reports as the start point of patrols etc.

I have seen following locations of this point in different sources:

1) Bishop's Rock of Scilly Isles
2) position 48N00 08W00
3) position 47N50 08N15

Anybody could help me to find the clue?
