#  Bletchley Park, Britain's Best Kept Secret - Codes and Ciphers in the
Second World War, by Tony Sale, The original founder and curator of the
Bletchley Park Museum and The Bletchley Park Trust, Note how completely
the people who saved the site, and restored and reconstructed the
equipment, and created the wonderful museum, have been spitefully written
out of the current official history of the museum. - an interesting
thought for all restorers
