I have a 1950s German slide projector (anyone remember slides?) which
I have been using with its German mains plug and an adaptor.

I decided to replace the plug with a UK 13A plug. Having removed the
German plug, I cannot remember which wire went were, and the colour
coding is unfamiliar to me.

There are three wires, coloured red, black and light grey. Can anyone
tell me which is which? I guessed at

red = live
black = neutral

but is the grey wire really the earth?

Definitive advice will be very much appreciated!

I'd really not guess about this.

Black used to be line on continental stuff with light blue as neutral.

The only safe way is to check with a DVM for a *dead short* between
exposed metalwork and one of the wires which should then be earth. Or
better still, open up the device and check physically. And replace the
flex while you're at it with the correct modern stuff.

The earth should be obvious as it will be connected to the metalwork. The
line will go to the switch if a single pole type.
