9010 * BRITISH WW-I D MK III FIELD TELEGRAPH/TELEPHONE SET:(39KB) This early set has a small telegraph key as well as a head-size- adjustable handset AND an early style leather encased single headset. It has been suggested that this set was used by the artillery or the baloon corps since the leather encased earpiece seems to be an early attempt at sound reduction. The leather case is stamped: "R.STAFFORD, 1916". The inner brass case is stamped STERLING 47486 L III XX 1916. The set was phonetically nicknamed the "Don three star".
9020 * FULLERPHONE WW-I FIELD TELEGRAPH/TELEPHONE SET: (17KB) This interesting British WW-1 Field Telegraph set is labeled: W.D.S.F.-K FULLERPHONE, MARK III No. 11077. 1918. It is based on the design originated in 1915 by A.C. Fuller. This design used 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 set is contained in a canvas covered wooden box with brass trim. The telegraph key folds out and the telephone handset is adjustable from 6 to 9 inches (to accommodate different size heads of British soldiers?). It also contains a brass plate with a very early and FUNNY phonetic alphabet. For example: A=AC, B=BEER, F=FREDDIE, I=INK, M=MONKEY, N=NUTS, P=PIP, T=TOC, and Y=YORKER, etc. There is also a wiring diagram inside the cover.

9040 1938 BRITISH ''DUMMY SIGNALLER'S KEY'':(20KB) This small key is inscribed with the amusing words: ''Key, Dummy Signaller's, MK II, 1938'' as though it was meant for use by signallers who were ''Dummies''. It has no electrical contacts whatsoever. It was actually designed to make the clicking sounds that are usually made by a sounder. It was used in training British soldiers to copy code by ear without the need for any electrical apparatus.

It is based on the design originated in 1915 by A.C. Fuller. This design used 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.

9114 * AUSTRALIAN BLUE POINT TELEGRAPH PRACTICE / TRAINING SET:(14KB) This set consisted of a key, battery, and buzzer. It was used for training potential radio operators in the Morse code. It was manufactured by Blue Point in the 1950's. Historian Herman Willemsen has provided the following information about Blue Point. The company was founded in the Sydney Australia suburb of Erksville in 1936 by a German immigrant, Frederick Boyd Dirks who named his company F. Dirks. The company produced bakelite products such as ashtrays, single strip heaters, and Morse key components. In 1946, the company name was changed to Blue Point products P/L. The name was inspired by the name "Blau Punkt", a German electrical supplier. In 1973, the company was purchased by Gerard Industries P/L (which was known for its line of Clipsal products). Blue Point keys were Identified by the words Blue and Point with a blue dot between them. Models X10B, XX20, XX20A, and XX20B are owned by Herman Willemsen.

9120 WW-II RAF BROWN ''BATHTUB KEY'': (13KB) This British Aircraft key was used on most of the RAF aircraft during WW-II. It is a BROWN bakelite bathtub-shaped key with a doorknob style knob. This is a flameproof design with a leather diaphram around the base of the knob. This key can instantly be set to send a constant transmitted carrier if the aircraft is going down by flipping a spring clip over the knob base. This freed the radio operator to try to escape.
