[Fern]

Looks like the lock inside a safe.

[-cristina]

No, sorry. This thing was invented more more earlier!

A Rube Goldberg clock works?

[-cristina]

[tipper75]

[Yvonne]

This isn't an easy one but that is okay
Found something called a Dry Material Feeder but it doesn't quite look the same so I'll keep on searching

[tipper75]

"CSF", is a huge hint

[Adventure]

I need a even bigger hint!
I really can't find it.

[tipper75]

No and no, it would be used in an industrial laboratory to monitor a process variable

[Adventure]

Some kind of Sample Mill?
It does look antique.

Not a permeameter..

[Timdogg]

Is it for measuring spirits? or something to do with the distillation process? (only guessing because its brass)

[tipper75]

Not a coffee grinder, it is a measurement device used in a certain process. This maybe too difficult

[Adventure]

My first thought was a coffee grinder.
