In June 2012, the NCMF received an anonymous donation of 12 monographs that are part of a series of reports published by the Bletchley Park Trust. The donor and reason for the donation are unknown. The report titles include, “The First Break into German Enigma at BP” by Brian Oakley; “Breaking Naval Enigma” by Frank Carter”, and, “Codebreaking with the Colossus Computer” also by Frank Carter.
The reports have been deeded to the NCM Library.
