HC-9 - Wikipedia

The HC-9 was a mechanical cipher device manufactured by Swedish company AB Transvertex. The HC-9 was designed after World War II and likely remained in use up to the 1970s. The machine was used for low-level communications.

Operation

The HC-9 made use of punched cards instead of the pin-wheel mechanisms of other machines (for example, the Hagelin M-209).
