BRITISH AIR MINISTRY KEY TYPE B1
This large Morse key is an early key with heavy current contacts at the front. It has more contacts and terminals at the rear for other equipment. May have been used on higher current transmitter circuits and/or remote operated from the actual radio transmitter sites via cables. More information later on. A nice key to use on the air when adjusted properly.
