A home built rack of electromechanical relays and uniselector switches assembled to imitate an enemy cipher machine, rows of relays with brass contacts, twelve uniselector switches with sweeping wiper arms, a jury of toggle switches on a plywood front panel, small plain labels of card tied to each unit, cloth covered wiring bundled along the frame, a teleprinter at the side, the rack standing in a hut workroom, a single work lamp from above at an angle, brass contacts and bakelite catching the light, the hut behind in darkness.
Jeder Verweis nennt seine Art. „Vorläufer“ allein wäre eine Behauptung.
