Usage conditions apply
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.
One of these two steel pieces is a rectangle with a smaller bar attached to a groove in one side and a hole. The second consists of two rectangular bars held together with steel pegs. The two pieces are bound with string (this is not shown in the photograph).
