Illustrated here is our copy of the Potsdam Map, the original is now displayed in the Churchill War Rooms in Whitehall. We worked with the Machine Shop in order to make this facsimile for display in a museum in Germany. Clearly the acetate had shrunk by the time the allies used it as reference because they then had to draw their proposed divisions across not only the acetate but also on the map itself where the shrinking acetate had exposed the map.
It is interesting to note that the outside case has its weight recorded of 18lbs clearly a necessity for the flight to Potsdam. Also the case is adapted, the internal rexine material has been cut away to enable the 1944 National Geographic map to be displayed, clearly a case of having to make do with limited resources.
The chain which encircles one of the handles, is cold riveted to itself, is padlock secured to the end of it is for securing the chain to another chain, not for keeping the folio shut but possibly for securing to the folio to the person assigned to carry it.
For the recreation of the rexine cover we used the expertise of Roy Bacon and his team at Marsupial Bags located at Brentford Studios, West London.
