What's this mystery object then.

[wildoliver]

Apparently quite heavy. Not mine I just saw it and was intrigued.

[JuniorD]

It has the appearance of a cleco pin aka a skin pin

It doesn’t look like it would function in the same way though

[wildoliver]

Much bigger than a cleco, quite heavy apparently too.

[LordLoveLength]

The knurled ring looks like it's part of a light fitting. Brass bulb holders have that, Is there a hole for a flex in the narrowed bit?
Absolutely no idea what it is otherwise

[SCEtoAUX]

The one on the right is a pen.

[JuniorD]

Maybe some kind of electrical connector or insulator from an antique brass lamp

It's a Blue Steel Stand-off atomic bomb initiator.
It will be highly radioactive and should only be handled wearing full NBC gear and remote respirator. .
What is it doing out of its' lead container?
Call your local 4X4 Active Response Team Immediately.

Well spotted! I've popped it in the post to you as your the expert!

Sealed both ends by the look of it, initially it had a lot of the look of a humane dispatcher but obviously isn't.

Some kind of hand warmer? Looks like it might have got hot at some point.

Although not too hot as it looks soldered together.

[Herbs]

Rifle oiler?

[vaud]

The brown woody thing looks like a table or bench, but hard to tell from this angle.

[JuniorD]

A black powered measuring tool for making bullets?

[wildoliver]

Definitely not a powder flask or measure, I suppose it could be a hand warmer although it's an odd shape for one, I worry what else it could be to warm......

Unlikely to be an oiler but I see what you mean, they tend to have a spout or more commonly a little spoon on the bottom of a lid, you would spill half the oil trying to use this I think. It looks to me like something fits inside it, like a protective case maybe, or a part of something else like an electrical conductor.

[JuniorD]

I would use it to contain the pen that is beside it

[SamR380]

Looks like something that would go to sea, maybe to hold a pair of compasses?

[coldel]

Medieval vibrator, they used to put bees inside it, screw it shut, and off you go.

[Tim-D]

I've something of roughly the same appearance / dimensions... a scalpel holder, RAMC ww2 issue.... mine has a wire rack inside with the 2 scalpels suspended in it...

Probably entirely wrong but......

[wildoliver]

I reckon either of the last 2 guesses are about as good as we'll get!

[JuniorD]

Is it a fancy pewter oil bottle for cased guns or rifles?

My punt is that is a part of some sort of mine detonator, sea or anti tank.
