MORSE KEY WITH LAMP, 1950's

The bulb with this key can be used for training by sending without the need for wires.

Your comments:

• I have one exactly like this. It has DGS or DCS stamped into the wooden base on the end. I looked it up on the internet and found nothing. It was badly tarnished, almost black when I bought it several years ago and took a file to clean it off, followed by a smooth file and emery cloth. It was on a larger board with a working PM2 type valve, Mullard audio transformer and a battery holder, probably for a grid bias battery, made from short strips of wood to hold it in place. It works with an H.T. of between 9-18 volts and my 2,000 Ohm headphones. I have used it on air but it's very noisy on the end contact giving a double click, a bit strange to use if no sidetone.
