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

DANGER DANGER DANGER
Some german appliances of that era had RED =EARTH and caused death when
imported into the UK and the earth was connected to live. This was one of
many reasons why we now have common wireing colours....
