DESCRIPTION
An Enigma Umkehrwalze D (UKW-D, D Reflector), a rewirable reflector introduced for use by the radio networks of the German Air Force (Luftwaffe) as a means of improving communications security. This example, found among other D reflectors, was dug up from the ground - most likely from a pit filled with discarded German radio and cipher equipment when Germany surrendered in 1945. Therefore, it does exhibit some damage where a sharp implement appears to have been used to destroy it, and also some corrosion.
Notes
Unlike the design of earlier reflectors, the UKW-D was a field-rewardable reflector. A modified version was also used by the German Navy (Kriegsmarine) in order to communicate with the Luftwaffe. As the UKW-D was not distributed very widely and introduced late into the War, it is very rare. This factor also stopped the UKW-D from causing as significant a headache for Allied codebreakers as it could have caused.
