WW1 MORSE KEY AND SOUNDER, 1916

Morse sending and receiving station. On the side of the unit (out of view) is a standard P.O jack No8 for Telehone plug No406, possibly for a headset, or even a telephone line.
May have been used by the Military although not marked as such.

Your comments:

• I have one of these keys, identical to the one shown here. It has a War Department broad arrow stamped on the top of the key. One assumes therefore that some of these were used by the military.
  
  The two vacant holes in the front of your unit, are in fact for the adjustment tools supplied with the key.(Missing on your unit). These were used to lock off the key and buzzer adjustment screws.The tools are brass-headed milled head screws, with a blued steel conical shaft, to fit the locking screws on the key.
