Fullerphone
was a special type of secured telegraphy set very popular in
British army since WW I when Captain George Fuller
introduced the idea of secured telegraphy over telephone
lines using low level direct currents. Same principles of
secured telegraphy were in use during WW II, too. Our
Fullerphone was manufactured in 1943.
