Many's the time I composed upon the form and then transcribed it onto a teleprinter with a reperforator attachment to make a 5-unit punched tape ready for transmission...
Happy days![]()
Wow! You're coming up with some superb treasures today Robin

I will have photos of the pink tape, but finding it might take some time. In the meantime, have a selection of various classificationsCitroJim wrote: 08 Oct 2023, 10:50

It would have almost certainly be for the 7B's then as they were plentiful. Not sure if the 444's were ever in place - never saw any anyway. Having handled a few 444's over the years I can only assume they were filled with lead to stop them vibrating or something.CitroJim wrote: 08 Oct 2023, 11:05
4-plyI could never see a Siemens T100 being able to manage it - they struggled with 3-ply unless perfectly set up - and no way a Creed 75 but I could well see a Creed 7B being able to handle it - They'd handle anything - noisily!!! And they were still widely used right up until the mid 80s to my knowledge...
All the Creed machines were just about the opposite... Tough, sturdy, bombproof, heavy, big, smelly and as I said, noisy...
I'm wondering now if a Creed 444, the staple of the GPO/BT Telex network, would... Possibly, they were also big, chunky and built like brick outhouses...
It always used to amuse me when looking at classified documents with pages marked SECRET top and bottom and the only text on the page reading 'This page left intentionally blank'bobins wrote: 08 Oct 2023, 11:20I will have photos of the pink tape, but finding it might take some time.
