Ten-Rotor T52 "Geheimschreiber" Cipher Machine
Dated 1944

This extraordinary Ten-Rotor T52 Cipher Machine, also known as the Geheimschreiber, represents the pinnacle of German wartime cryptography and stands as one of the rarest encryption devices from World War II. Manufactured in 1944 during the final phase of the conflict, this sophisticated cipher machine—codenamed "Sturgeon" by Allied intelligence—was exclusively deployed in high-level German command centers for their most sensitive communications. Its exceptional historical significance and extreme rarity make it arguably the most important cryptographic artifact available to private collectors today.
