The machine sounds very similar to the teleprinters used for the Aeronautical Fixed Telecommunications Network (AFTN) which is the way most flight plans and notams etc are distributed through the ATC system. Nasty noisy things in the 60's when I started. They were able to cut and read paper tape and I believe were compatible with the radio teletype. It is not so long ago that a lot of the transatlantic traffic carried radio teletype, more convenient than HF RT as anyone who has been driven deaf by it will testify.
