Cambridge Instruments Slide-Wire Potentiometer

This is my Pye resistance box, exact same as yours on the inside Alan. I've put a wander plug on it for scale.

Unfortunately there's something wrong with the 8 thousands setting which I can't sort out. A story for another day.

Actually, looking at yours again, I see mine has another terminal. So it isn't quite the same!
