I'm trying to find the purpose of this device, anyone recognize it or the logo?













Thanks for taking a look.

looks like some kind of tool to ensure vertical alignment

Brevet likely means patented by the company whose logo appears above "Brevet". Arrow H, dunno...

It looks like a cylinder could be held between the posts and plunger on the bottom, pulling the trigger would release it. Can't think of a good reason for it though, maybe a game of some sort.

makes sense. i thought it would be something to align pipework. a pipe could be held by the device with the rod hanging down. you look through until the pipe is vertical and you can then release it.

Find out tomorrow

Thanks for the link, but actually that's my site, I don't know the answer for this one and I'm trying to find out. I hope to have an answer by tomorrow but that remains to be seen.

looks more sinister than something for pipework, something for the dental chair, like a root canal nerve extractor alignment probe

Whatever it is, It looks hand made, or at least hand assembled, rather than mass produced. I would guess that either it's pretty old or for a specialty field where they don't sell thousands of them...

Nah, looks like something to do with piping however a more precision line of work. Definitely for aligning something cylindrical, hence the 2 pick up points and release point mechanism. Though what this tool was specifically created for must involve a shrink fit.

Behold, if it comes from country of William Tell it might be associated with some kind of weapon

like for a paintball bombardier's bombsight!

The bit sticking down looks a little like a plunger on an oil filled diaphragm carburettor, with the 2 downward studs and sprung bit (with trigger release) being used to hold round the top of the bell-end (stop it). Then the sight, with mirror is used to align for adjustment.


I did also wonder if it was a variation of this?

I think I got it. This tool is used in Glarus to conduct pep smear on cows.

Definately a device for ensuring alignment of something with the horizontal plane and also to ensure alignment on the roll axis. Could be associated with perhaps checking something that transports a liquid is aligned.

The two short shafts and the trigger mechanism are the keys here for a solution. Also the plastic over the mirror is a clue. My guess is that the trigger mechanism is connected to or placed on something, perhaps a pipe?

To protect the mirror from the spray of blood?!

The clues are all there.....Prince Albert's jeweller had one.....

Looks like an advanced gun used for the game Crossfire with steel ball bearings.

A quick search of related images on Google leads to some worrying results.

Could be a trainings device for pistole shooters. You stretch out your arm and look at the pendulum through the mirror while you pull the trigger. It looks like the trigger is not triggering anything at all.

The purpose of the plastic cover is to protect the mirror from miss alignment. It has to be in a perfect 45 deg angle..

Tried to look up the logo in the IGE|IPI registry , but had no luck.

It could also be an old school version of this
But what is the trigger for?

Or this


Q: Is this an halfway mirror?
