Swedish Transvertex Pin & Lug Cipher - 1950s

KRYAPP-301 cipher is a derivative of the Hagelin ciphers, but uses a punch card to replace pin & lug settings. KRYAPP-301 is the military version of the Transvertex HC-9, which may stand for Hagelin Cipher number 9. One of 16 reciprocal alphabets is selected from a second card in window (shown extended).
