Hagelin Pin-wheel C-446 → ← M-209
Pin-wheel cipher machine
- this page is a stub
The C-443 is a mechanical pin-wheel
cipher machine,
developed in 1943 by Boris Hagelin (later: Crypto AG) in Sweden.
Apart from a few manufacturing differences, the machine is identical to the
Hagelin C-48A that was released a year earlier (1942) and which is similar
to the M-209
[1].
|
A complete description of the C-48A is given in the original 12-page manual of
March 1942 [2]. In a separate document, that was released one year later,
it is explained that the C-443A is only marginally different from the C-48A
and that the two machines are fully crypto-compatible [1].
The image on the right shows an original C-443A machine in extremely good
condition, that was used in Uruguay. It was rediscovered in 2013, complete with
all four keys, and barely shows signs of usuage. It is assumed that this
machine was purchased for evaluation purposes.

The C-443A was succeeded by the C-446A, which was nearly identical and featured
only minor manufacturing improvements.
For further information about the operations of the C-443, please refer to
our page about the C-446.

Apart from a few minor manufacturing improvements, the following machines
are functionally identical [A]:

Although this machine is functionally identical to the C-443, its
enclosure (i.e. the top lid) is higher to accomodate two full paper reels.
