This is a vintage Manhattan Electric Supply Key and Sounder (K.O.B.). It was possibly used by the railroads. There is a set of numbers stamped on the bottom of the lever (N186 178). I don't know what they mean. I tried to get them in a photo, but it did not come out readable. 5 OHMS is marked on the board. This unit has been cleaned, restored, and is in working order. Please feel free to ask questions.
