When I was a child, I was dreaming to emit in Morse. At the primary school I had undertaken to
learn the Morse code which I had found in the dictionary "Larousse".
When I found this Morse signal key, at the secondhand trades of Lyon, I immediately bought it.
This German model is identified as "Junker Honnef / Rh D.B.G.M." (Deutsche Bundesgebrauchsmuster).
The large notched wheel controls the electrical contacts spacing. The small wheel, by the mean of
a spring, the pressure to exert to rock the key. The adjustments are very precise.
The Morse code was sticked on the bed plate, but does not seem to be of manufacturer's origin.
In 1926, engineer and marine captain Joseph Junker founded a factory in Berlin in which he
made radio equipment. One of his first products was the Junker Morse Signal key.
