Does anyone know what this is?

It's obviously a Stargate.....

Old money currency converter/calculator? - mention 240 a lot - i.e. old pence in old pound....

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.

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

Looks like some Kind of electro mechanical calculator converting base 16 into fractions.

No idea what it might have been used for.

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

Could it a contraption for working out the date of Easter sunday?

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!

Something that belongs here obviously:

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