This key is a very rare find and has not been tested. Unlike most keys of the period, which were a single current system with current flowing in one direction, this is a double current system which uses a polarised relay to neutralise the residual charge on the line. Current flows in one direction through the relays to produce the Morse code dot or dash, and flows in the opposite direction to produce the spaces. This enabled the user to handle higher rates of data.

Mounted on wood it is In reasonable condition, with discolouration/scuffing of the brass/bakelite and wood. I haven’t attempted to polish it.
