Holy cow batman, that's old. When I was a tech in the PMG many many moons ago we used a similar technology, from memory a carpenter relay was involved and moved bars with notches to give the electrical pulses for the characters the old telegram machine.

Another ex "TIT"
Worked on the Swedish Cross Bar Exchange in Lakemba Sydney, the mechano set we called it. Still remember though running around the old exchange with a butt watching for selector arms to move and get numbers, ohhh the noise...oh the fun....lol
Good lord ontos, my first job as a TIT was to help pull all the step by step stuff out of Blacktown exchange As a TIT, then I ruined my new dust coat by taking SG readings as they commissioned a new battery bank. I joined the program in 1965 and started my training at Homebush. I was in section 1
I would have been in Lakemba round that time. My apprenticeship was taken over by the PMG (Dad was a grade 2 Pay Master) from a typewriter/calculator mechanic. Ended up after that doing an electricians course. Finally ended up designing and commissioning closed circuit TV (CCTV). Worked out my days till retirement as an assistant ranger on the Scenic Rim Qld. when COPD started to catch-up with me. A rolling stone gathers no moss.
