E74a British D. Mk. V., 1940

Visit http://fieldphones.org/episode74/ for additional information. Presumably the D.Mk.V was developed before, but introduced in 1939 (Release date of Manual; and I have never seen one with an mfg label prior to 1939). It is the successor of the WWI D.Mk.III. It was also used by the Australian and Canadian Army and other Commonwealth armies. After WWII a good number of D.Mk.V. were refurbished into D.Mk.VI. for the Italian "Esercito di Transizione". The here documented are a British army set from 1940 made by "P.T.&E.W. Ltd." and a Canadian army set from 1943 made by "P.E.W. Ltd.", both manufacturers are probably the same Phoenix Telephone and Electric Works. Unique features I like the set's design, but the identified unique features are both drawbacks, quite strange design decisions in my opinion: No magneto built in, can only do buzzer calls, but has a built in ringer to receive magneto calls. Headgear receiver in series with handset, if headgear is damaged set stops working, headgear terminals have to be shortened out, and to replace headgear the set has to be completely dismantled.
