QuoteWhile on service in the 1950's I had been running multi channel VF telegraph equipment over land lines to radio transmitters. The signal originated on paper tape in Murray code, there was an offset sprocket continuous punch line with two holes below and three above so it could only be run in the correct manner.This was created on a keyboard only machine then run a 66 baudes the receiving machine converted the signal to be printed on a Creed teleprinter. On return to UK in the mid 1950's Linotype were advertising for "teleprinter mechanics" with experience of this type of work. I turned the job down for better paid GPO work. In 1960 GPO opened Fleet Building Farringdon St, this replaced the old Central Telegraph Office where telegrams were sent all over London by pneumatic tube.UK and world wide by wire or radio with teleprinters and provided a "dial up teleprinter service" (putting it in its simplest form of words. (this building has in turn met its demise and a new office block nears completion. This new building also includes the former site of the London Evening Standard.In the 1980's I had chance to buy one of these TTS Linotypes when a school of print closed, (my 1908 model 4 had finally run out of spares) but a 48 came on the market so was better for my purpose with the higher number of channels.
