Apart from the fact that it would be unlikely to have been wired

copper wire.

Or alternatively the earth connection was made via the screws from
the conduit.

would no longer be safe to rely upon it for earthing purposes.

There is a problem with half a century old rubber wiring. Its often in
such bad condition than any disturbance is liable to cause shorts,
fusenpoppen, shock or fire.

That reminded me of;

Poken Verboten

Achtung alles lookenpeepers. Das machine is nicht fur gefingerpoken und
mitten grabben, Das easy schappen der springenwerk, blowen fusen und poppen
corken mit spitzen sparken. Is nicht fur gewerken by das dumkopfen. Das
rubbernecken sightseeren keep hands in das pockets, relaxen und watch das
blinken-lights.
