HISTORY OF THE ITEM
In World War I, the British used Mark III Short-Wave Tuners in the trenches. Jonathan Hill writes in Radio! Radio! that this early crystal set "was used by the R.F.C. ground stations for the reception of Morse Code signals transmitted from aeroplanes flying above the battlefields of the Western Front. The pilot's job was to direct the gunfire of artillery batteries on the ground via an R.F.C. wireless operator attached to each battery. With a clear view of the battle scene below, the pilots would transmit in Morse the coded position of the enemy and the message would be relayed on to the gunners who would then take the appropriate action."
This procedure may seem primitive by today's standards, but it was a technological revolution in its days. It allowed artillery soldiers to be much more accurate than they could have been without knowing the enemy's position and the results of their shelling.
Marconi's Wireless Telegraph Company first developed the Mark III Short-Wave Tuner in 1915. From 1916 on, several variations of this tuner were manufactured by a number of companies, including Robert W. Paul, the W/T Factory, A.T.M. Company, and Johnson and Phillips.
This receiver was purchase to a person living in the countryside of a province of a Southamerican country, who stated that it was property of his grandfather.
He told him that in 1925 the Prince of Wales stayed there for a few days, and it was part of the equipment personally operated by the Prince, who was fond of broadcasting, and that the handwritten entries were made by the Prince himself. These claims must yet to be checked out (copies of entries were already sent to IWM to verify calligraphy)
The fact is that the equipment is from 1917, the entries were made in 1919, it keeps all spare galenas intacts and the watch is still there, so that shows that previous owners were very carefull about handling it.
