Western Electric 35 Test Set Top
Here is the top view of a Western Electric 35 Test Set showing the four J.H. Bunnell 6b keys in place.
RAF NR: 1 KEY WITH SMALL LAMP
This key, an RAF No: 1 (About 1924) from England received years ago is mounted on a wood base measuring 5 inches(127mm)long by 2 1/2inches(68mm)wide by 1/2 inch(12mm)thick. It has a good solid feel to it when used. The extra two pieces of wood inset in the ends and the terminals remind me of many Marconi morse keys that were on wood bases. Not sure why they added the small lamp with two terminals, maybe for training.
