1942 · Pulse Timing Radio Navigation · Werk 788 von 1.871

A radio navigation indicator of 1942 on the navigator's chart table in a four-engined bomber at night, a grey-black metal box thirty centimetres wide with a round glass screen in its front glowing a plain soft green, rows of plain black knobs beneath, in a cradle beside it a long black receiver box fifty centimetres long with a pale round socket on its end face, thick cables between the boxes, on the table a chart sheet at a flat angle, soft in focus, a hand in a brown leather gauntlet on one knob, the curved wall of plain dark painted metal, greenish glow from the screen on everything.
