In the fourties, Moser Baer, Sumiswald, produced high speed telegraphy equipment consisting of a tape punching machine (a keyboard perforator), a punched tape transmitter and a morse code printer. The precision mechanics company Moser Baer does still exist nowadays, today the Mobatime company producing the famous Swiss railways clocks is a successor of the original company.

Morse code printer

The Morse Code printer UV200a is part of a high speed transmitting system constructed by Moser Baer in the fourties. It is still unclear wo which high speed telegraphy system this printer did belong to, it seems never to have seen use with the Swiss Army.

Morse code printer ist used to print the morse signals of a high speed telegraphy signal, which is too fast to be copied by ear, to a paper tape. The paper tape can be translated from morse code into clear language at a later time.
The system was intended to be used for transmitting high speed morse code to be transcribed by the operators later, as it turned out that several signalmen could not copy the standard morse code transmissions at a decent speed.
It turned out that copying the morse code from the printed paper tape was ver time consuming as well, so the procedure was abandoned after a few years and more effort was given to regular morse code practice for the wireless operators.

I would be interested very much in additional information about where and how this equipment has been used, the colour of the cabinet and written information about the use of high speed telegraphy in the Swiss Army leave the impression that this equipment has been used outside Switzerland.
