What is this?

Towel or flannel holder would be my guess.

The insteresting aspect is the pointy bits that obvously go
into whatever it's screwed to. Earthing function perchance?

It's a teaspoon flange calibration device, with a built-in vortex flute.

Is it an early mockup Blib 87s?

If so, I have heard the dodgy fellow himself if trying to buy them all back, so let's hope he doesn't show up here...

Smut aside, how big is it? I've seen similar, used to spark up gas lighting. Crank a handle and a spark is created between the 2 brass balls, lighting a stream of gas for a street light. Guessing around 50mm?

Or it's an Edwardian electro-ejaculator.

Give it a sniff, OP. If it smells vaguely of gas..... it could be either.

In regular usage, it should smell of beluga caviar steeped in Absinthe, but judging by the photographs, it has hasn't been properly used for quite some time, although the patina would suggest it has had some quite vigorous use in the past.
But it looks as though it has plenty of life left in it, and I would be quite happy to take possession, as it were.
What do you say, OP?!

In that case it might be more to do with increasing cardiac performance.

We all know absinthe makes the heart grow stronger.......
