11-001. Swiss, early 3rd quarter 20th century, manufactured by "Crypto AG," but with the original metal trade labels removed before the units were released. The CX-52 is a compact, hand-operated, tape-printing, mechanical cryptographic rotor machine built into a very rugged 8 1/2" x 5 3/8" x 4 3/8" metal carrying case, painted military olive drab. Opening the top and the inner lid reveals 6 key wheels, drum disks, setting knob, drive knob, encipher-decipher knob, etc. The machine is provided with a printing mechanism which prints both the primary and the secondary texts at the same time. This CX-52 is in very good working condition and comes with the original oil can, tools for the rearrangement of the pins & lugs, and receptacle for spare ink rollers. Also included is an original canvas case for the machine and a canvas carrying strap.

The design of the CX-52 is such that it can be transformed into an electrically driven keyboard operated machine by the addition of an electric drive unit, designated the B-52, which comprises keyboard, setting and driving mechanism, 12 1/2" x 8 1/2" x 6 3/8", also painted military olive drab. When an electrically operated machine is required, only the outer cover of the CX-52 machine is opened, and the machines is slid onto the B-52 base and locked into place. This B-52 is also in very good working condition, with its original power cord and spare fuses in the base.
