This is an aluminum vintage engine order telegraph with an iron base made by “Nippon Zosenkikai CO LTD”. This vintage engine telegraph stands 43″ inches tall. It has twin dials that measure 14 inches wide. The top head section of this unit is 16 1/2 inches thick. The base is about 15 inches wide with 6 mount holes. This is an electric telegraph and its working condition is not known. I have never re-wired one of these telegraphs, but several of my buyers have had success in sorting out the wiring.
The base unbolts from the top, so we can ship this item with no problem. This vintage engine order telegraph weighs about 130 pounds.

An engine order telegraph or E.O.T, was a device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed. In early vessels, from the 19th century until about 1950, the device usually consisted of a round dial about nine inches (~20 centimetres) in diameter with a knob at the center attached to one or more handles, and an indicator pointer on the face of the dial. There would also be a revolutions per minute indicator, worked by a hand crank.
Traditional E.O.T.s required a pilot wanting to change speed to “ring” the telegraph on the bridge, moving the handle to a different position on the dial. This would ring a bell in the engine room and move their pointer to the position on the dial selected by the bridge. The engineers hear the bell and move their handle to the same position to signal their acknowledgment of the order, and adjust the engine speed accordingly. Such an order is called a “bell,” for example the order for a ship’s maximum speed, flank speed.
