Agree with above comments. Can anyone remember a period in time when many domestic properties were wired in pvc singles!
The single lives were looped from switch to switch and the neutrals were looped from light to light. An absolute pain in the neck if a new complete light point with switch was required. The existing light points would only have a switch wire and neutrals. All had earths though.

Sounds like a normal conduit wiring system to me...........
Been on job today house built 1963 wired exactly as you say in singles permanent live we're red sheathed singles and sw lives were grey sheathed, with a green earth ran around all points, although these were terminated into fittings apart from when some muppet changed the fittings at a later date and left one of the two earths in the ceiling, resulting in most of the circuit having no earth.Agree with the above(s), tended to be the cheaper contactors that's only used twin and skin, better domestic installs had CPC's right from the start of pvc, I tested one the other day 1962 and it had cpc, admittedly twisted together above all fittings ;-)
We started installing cables with cpc in 1963 just before the 14th Edition Wiring Regs.
Before that we just ran a Earthing cable to each lighting point.
On Commercial & Industrial Installations we used the conduit as the Earth
AgreeWell, I started work in 1972 and we always ran an earth to all lighting circuits.
