... I downloaded several 27"X22" Kriegsmarine Gridmaps today, printed the sections and spliced them together. they look great on this massive computer desk of mine (i use very little of the desk space on one side)
The charts are as follows:
Atlantic Ocean KM Gridmap showing Europe Africa greenland Iceland and the US/ Central America
Waters Around England/ Gibralter
Far North Atlantic covering the area of the western approaches
they look fantastic when carefully cut out and taped together and could almost be used for plotting intercepts and navigational plotting though i doubt i will go that far! if laminated with large laminating sheets one could easily plot all of their sinkings on the charts over the span of a career and use a marker to mark mine fields and net positions as well as known convoy routes
