Hagelin Pin-wheel CX-52 → C-52 →
Known C-52 and CX-52 slide bars
Hagelin's pin-and-lug cipher machines
– the co-called C-machines,
or pin-wheel machines –
all have a revolving cylindrical drum, or cage, with sideways
movable bars, the so-called slide bars, that control the stepping of the
pin-wheels and the print head. The Hagelin C-52 and
CX-52 cipher machines have 32 slide bars in their drum, that are
interchangeable between the two machine types.
Below is an overview of all known slide bars, as indexed by Bart Wessel in [1].
The bars that are shown in grey can be fitted with lugs and are known as
luggable bars.
The bars that are shown in red can not be fitted with lugs
and are known as unluggable bars.

Below is an overview of the Standard A set of slide bars, as it was
supplied with the CX-52a. Note that the suffix 'a' was a secret
designator, that was not printed on the ID-tag of the device.
A good example is the
CX-52a with serial number 334323
from the Crypto Museum Collection.
