I know very little about how this worked so far - please send me e-mail with corrections, clarifications, additions, etc.
At shore transmitting stations, Morse code messages could be punched onto paper tape and then sent via a CW or FSK keyer which controlled the transmitters. Normal shore-ship transmission was around 20 wpm, but high speed links between shore stations could run up to 400 wpm.
At the receiving end of a high-speed link, Morse was recorded in ink onto a paper tape - the tape could be read by Radiomen who printed the messages using a typewriter (mill). Code recorders were also used for intercept work.

Good Navy paint beneath the grime |
Ah that looks better |
Capstan and pinch roller |

Green points to pen tip Magenta - pen motion Blue - tape path? Yellow - missing piece? roller? |
Better shot of pen tip between adjustable stops. |

I have got the pen and capstan motor working, but am missing some piece that guides the paper tape past the pen - please send me e-mail with any info or photos of this unit |

In the 1970's there were automatic Baudot-Morse and Morse-Baudot converters >> I need more info on this
Designed to serve as an interface between a conventional communications receiver and the Morse-to-teleprinter code converter.
Converts international Morse code into standard 7-unit start-stop (Baudot) code.
