Cyclometer

Cyclometer, devised in the mid-1930s by Rejewski to catalog the cycle structure of Enigma permutations. 1: Rotor lid closed, 2: Rotor lid open, 3: Rheostat, 4: Glowlamps, 5: Switches, 6: Letters.
The Enigma machine was an electro-mechanical rotor machine with a scrambler consisting of (from right to left) an entry drum, three rotors and a reflector. It was available commercially from the early 1920s and was modified for use by the German military who adopted it later in the decade.
Marian Rejewski, ca. 1932

The cyclometer was a cryptologic device designed, "probably in 1934 or 1935," by Marian Rejewski of the Polish Cipher Bureau's German section (BS-4) to facilitate decryption of German Enigma ciphertext.
