I have 10 to 12 Kriegs Marine Grid Maps printed out! The first one is titled The Waters Around England! That map has a key showing Quadrant 41! There is no author's name or Copyrights on the maps!
I'm wondering where they came from!
Other Maps:
Baltic Sea
The Northern Theater
The Siberian Sea Route West Sector
Central And South Atlantic
West Atlantic
The Med Sea West and East!
North Atlantic
