notes: label: Description
content: This is a prototype rotary cipher machine component made by the American inventor Edward Hebern. The badly rusted machine has a steel frame with a keyboard in front, a motor on top, and a cylindrical device on its side on the top. Numerous wires lead into the cylinder, and it is attached by a gear shaft to the motor. There is a capacitor in back. There is a cord on the right and another on the left. Dimensions do not include cords. The keyboard has three rows of keys, arranged like a QWERTY keyboard, with no top row. The second row has a "SHIFT (/) LOCK" key and the bottom row a black "SHIFT (/) KEY". The object resembles the keyboard part of 1991.0190.06, but the keys are white on this machine.
