It appears to be designed to be permanently mounted, so perhaps measuring something environmental?

Have you tried unplugging and plugging it back to the mains?

No idea what it might have been used for.

No idea what it was designed for. I use one to summon the servants from downstairs.

It's Barrydidit's new smart phone to go with the electricity he's had installed. They are catching up in Huddersfield.

Its the financial calculator that Gideot used to work out, what a Brexit was going cost per person, in the UK.

Actually, that might be it. ISTR there is a 19 year cycle, and the dial seems to stop at about 19.

See https://en.wikipedia.org/wiki/Computus (although I don't have time to study that page now)

Seriously, could it be some kind of resistometer? On the right are what look like a pair of contacts bridged by a wire.

Surprised Zeity doesn't recognise it, or use one of them every day!

Actually it looks distinctly Satanic, probably a Ouija board created by Fermat to conjure up demons. Be careful, the chap was no fool.

Is it a tool for working out Egyptian Fractions?

Egyptians expressed fractions as a sum on unit fractions with a numerator of 1, so:

2/3 = 1/3 + 1/4 + 1/12

So go on then. What is it?

There are numbers around the holes and numbers around the inner ring too. Is there meant to be a card that goes on the centre?

The only thing I can work out is that the second line has 1/12 + 1/48, and that's about 0.1 and its a tenth of the way round the circle. Can't make any sense of any of the other fractions though.

No idea, hence asking. There does appear to be a table on the bottom right equating numbers on the ring to multiples of 16 which made me think it might be an early hex calculator but beyond that I'm stumped.
