DESCRIPTION
A transit case for a KL-7 cipher machine. The case has a metal plate on the lid that reads: 'National Security Agency Carrying Case CE 80754'. The serial number that follows is illegible. In the lid, there are sections to stow a power cable, work light and a spare ink ribbon. There is red paint over the original green paint which may have been added to repurpose the case for a civilian use, possibly as a tool box.
Notes
A replacement to the SIGABA machine used during the Second World War, the KL-7 was developed by the NSA in 1952. In addition to the US military, it was also issued to NATO countries. This KL-7 transit case was found in Canada. The KL-7 was used into the 1970s, eventually being withdrawn from service in 1983. It was declassified in March 2021.
