Original British WWII Fullerphone MkV Field Telegraph Set in Case with Strap - dated 1944

Item Description

Original Item: Only One Available. This is a very nice example of a British WWII Field Telegraph set, known as the Fullerphone Mk V. This set consists of a key, battery, and buzzer, and is contained in its original wooden transit chest, which has the correct khaki sling still attached. The set itself is dated 1944, and still has the correct buzzer installed. The chest was designed to hold the included headphones, and slides forward inside the chest into the operating position, much like British Field Telephones.

These units used for field communication over wires, as the simple Morse Code was much more reliable in many cases than voice telephones. These are based on the design originated in 1915 by A.C. Fuller, which uses Direct Current telegraph signals, which were impossible for the enemy to intercept and decode. The design allowed much better security than the American and other 'buzzer sets' which sent code signals in the form of AC buzzing voltages. The fullerphone decodes the D.C. voltages by using an interrupter and handset or earphones.

The carrying case measures 11 1/4" W x 6 1/2" x 6 1/2", and is very nicely marked with white paint stenciling:

YA 6916


MK. V.

The canvas strap is also maker marked and dated 1943, with various inspection marks.

This example is offered in good condition and appears to be complete with all components and the headset. We have not tested it and cannot verify functionality but appears to be complete. Ready to display!
