The (Hagelin) C-52 and CX-52 were cipher machines manufactured by Crypto AG starting 1951/1952. These pin-and-lug type cipher machines were advanced successors of the C-38/M-209. The machine measures 8 1/2in × 5 3/8in × 4 3/8in. The device is mechanical, but when combined with an electric keyboard attachment, the B-52, the resultant system is termed the BC-52. The B-52 is larger, measuring 12 1/2in × 8 1/2in × 6 3/8in.
After the success of the Hagelin C-38 and the US M-209 as tactical cipher devices Hagelin Cryptos (Crypto AG, Switzerland) decided to developed a cipher machine that could resist extensive cryptanalysis to open the door to the market of high level military and diplomatic encryption. In 1952 the C-52 was introduced and, as Devours and Kruh wrote, "caused ripples throughout the cryptanalytic community". The C-52 raised the security of pin-and-lug type devices to another level. Thanks to its brilliant design this all-mechanical machine has a tremendous keyspace and cryptographic strength. When the variable key elements are selected carefully the CX-52 provides even in this computer era a powerful encryption. Within a short time the C-52 and CX-52 were purchased by more than 60 countries and remained popular for decades. This makes the Hagelin C-52 and CX-52 the most successful Cold War era cipher machines.
For those interested in these historical Crypto machines, I do have five caches using them. In order of easy to more difficult; "Hagelin" BC-52 Cipher Machine, "Hagelin" M-209 Field Encryption Machine, "ADONIS & POLLUX" TSEC/KL-7 Crypto Machine, "Purple" aka 97-shiki ōbun inji-ki, and Belle Isle Marsh Enigma
Everything is set default on this one, so all you have to do is figure out how to "build" it and use it properly.
