Description
The American inventor Edward Hebern (1869-1952) designed a series of machines for encrypting messages. The Smithsonian collections include a few of these as part of accession 1991.0190. Like many inventors, Hebern accumulated a variety of spare parts. These are some of them, part of museum transaction 1991.3033.
This component consists of a steel center piece and one black bakelite side of a rotor. Spring contacts are around rim instead of in L-shaped pieces. The metal center piece has a relatively large hole. Thre are no wires. Letters are notedaround rim. This object is similar to 1991.3033.01 and 1991.3033.02 except for the size of the shaft hole; the contacts; and the incompleteness.
