Arran - I bet you're right probably vinyl, there was no rubber smell when desoldering it, which you often get with the older stuff. I did start wiping it down with solvent, which worked well until one of the wires detached from inside the bulb holder... so I replaced.

The wires were black, and the insulation still flexible.

There is also clear vinyl tubing that covers the short length of FM balanced feeder. This was completely grey and dusty looking - I thought it was simply grey tubing, but it cleaned up rather well, and is now slightly yellowed, but transparent, and the red plastic of the feeder wire can be seen.

Most of all, I'm happy that something isn't on the fritz inside the radio, which I was utterly convinced was the case for a while. This one had such a catalogue of noises - Mrs H called it snap crackle and pop, LOL!
