Been playing with an old toy train transformer/controller (H&M
Powermaster, for those with long memories), circa 1960, 0-12v DC output,
up to 2.5 amps. The mains lead, woven outer (like an iron) contains
rubber covered wires (old colours, of course), and the rubber has
perished.

Changed for a modern flex, but the original earth was soldered directly
to the all metal chassis. I have soldered a tag to the earth, and
attached it to the chassis with a nut, washer and bolt. Metal all
cleaned and shiny. Hope that is OK?

Yup.

Curiously, although the mains lead was rubber, all the internal wiring
is PVC, and looks fine. Probably constructed about the time rubber flex
was being replaced by PVC?

Dunno why they'd have used that type of mains lead. Perhaps they had
plenty in stock?
