So am I right in assuming that 4C used to sit at one? 
You assume correctly, sir, but not one as grand as that - it was, shall we say, somewhat more 'provincial' - the oscillator/measuring sets are built into a wooden housing probably knocked up by a local chippy when the station opened in the mid fifties.
Sorry about the quality - it's a scan from a fuzzy transparency
b*cat will no doubt espy the LMS 35A top centre
That was in a repeater station on circuit provision and maintenance in the 80s.
In the late 60s I did a brief stint on a Test Desk, then graduated to the Trunk Maintenance Control Centre (TMCC), which was like a test desk but geared to telephone trunks and private circuits. Fantastic job - faulting circuits and co-operating with London Faraday, Ennisklillen, Wick and all points between.
What I did come to realise over the years, is that employees of the company back then had a far greater grasp of electrical principles, than they do today. 'We' just connect to the wires at a POI (Point of Intervention), and run a RUE (Remote Unit Emulation) test, and it tells us whether it's passed or failed. Easy street.
Aye, BS, it's a different world. Tha knows not what tha's missed.
