CODEX - an early British tactical code "machine" that looked like a folding pocket (bellows) camera. It apparently used two strips of paper (one with the vocabulary, the other with the code groups) which had to be stuck together then wound onto the roller. Held about 200 commonly used phrases, spelling, numbers, etc. It replaced by SLIDEX around 1943.
