Not strictly on-topic for this forum perhaps
but there seem to be ex-BT linespeople on
could anyone say what this cable was used for? (its provenance is definitely GPO)

Yep, that's a hunk of the [very] old style lead cable. The paper separates the pairs. Still aware of some lengths of it in the ground and carrying working circuits round this way. Have faulted on it a few times, but have not had the training to make/close a joint on it, only a few that can now. It's absolutely fine, til it gets wet.

Looks to be a 'travellers' dream, copper wrapped in lead. smile

roughly what time period was this cable "current"?
what was it used for? there is some dispute here whether it was telegraph or telephone.
would it have been used for subsea links?

Yes. It's a marine cable. Hence it is heavily armoured.

Looks like an old coax. If it is coax, it used to carry a lot of traffic because there is a lot of tubes there.

Could be SHEFA-1

this cable sample definitely predates SHEFA-1
