As part of an on-going collaborative project between KMi’s Centre for New Media, and the Bletchley Park Trust, an original Enimga encoding machine was brought into the centre to be photographed for a variety of multimedia and web materials. Pictured is Peter Wescombe, a trustee of the park, demonstrating the function of this Kreigsmarine (German Navy) 4-rotor machine, used from the beginning of February 1942, to KMi’s ‘chief scientist’ Marc Eisenstadt.
