Your mention of 3/.029 caught my eye.
Back in the early 1970s, our telephone number was the Name of the Exchange 3029 a few years later 54 was added and it became 543029. However in between that I was thinking one day, I know that number and thought that I knew someone else with a number ending 3029. Then it dawned on me, 3 strands of 0.029 inch diameter wire as used relatively recently for lighting circuits, now 1mm ^2
Annoyingly after our house was built we had to wait months for the Post Office as it was to connect the 30 or so house to the local exchange. All but one house had a telephone line. Then a few years later the house next door to ours, the one without a phone, wanted one. So the Post Office decided that ours and the house across the road would become party lines - the house which then had the new connection got an exclusive live!
We had two phones, permanently connected as they were then with the bells in series and utilising the ring capacitor in one of the phones. Since there was a concrete path all around our house, they could not fit an earth rod, so instead connected one of the 4 cores to the main earth terminal of our electricity supply. Not a neat job. The Engineer simply opened up the insulation of the 4-core cable and connected a wire to it and wrapped it with insulation tape. The other end going into the earth terminal.
It proved annoying; especially when I was away at sea and after waiting an hour or so for a telephone call home to find that the phone number was engaged when it wasn't. The way out of that then being the Post Office Radio Station at Portishead to get the local operator to break in on the call taking place and advise of an incoming call.
Those were the days?
