The Code Book from Berlin

"This codebook comes from Berlin and was donated by the generous Mr. Woolley Fergus. The origin of this codebook can be traced back more than 70 years ago. Hugh Rancy, Churchill's translator, was the first British man allowed to enter the bunker at Hitler's hiding place. He was told by Soviet soldiers that he could take some things from the bunker and bring them back to London as souvenirs. In the conference room, he took one of the Brookhaus Encyclopedias and the codebook on the shelf."
