Even if it's rubber it's not a foregone conclusion that it's perished. I pulled out some rubber insulated & rubber sheathed singles from my own cellar/basement that must have been there since the 1950s at least (complete with round switches on wooden blocks) - and they seemed to be in perfectly decent condition throughout and even passed an IR test without problem.

I have found a length of rubber 2-core cable under my own floorboards. Difficult to date because the accompanying empty Woodbine packet was unchanged for decades. Given that the house was re-wired circa 1982, that cable must be somewhat older. I have also recently found a fragment (6") of steel conduit with fabric covered singles, which are in good condition.
Some of the gas pipes, which date back to 1924, are no longer serviceable.
Andy, as I said, heat is the long term problem with rubber becoming brittle, I find that lighting circuits are not affected since usually overrated.
