Cheers OldMech - lets try this - and it isn't a valve or solenoid manifold.. Good luck - the top has been removed so you can see the interior...

Is a laser bell? Or laser related?
Is it an injection mold?

That must have been too easy.. I will hunt through my work files a bit harder next time.. we call them a laser pump over this side of the world, but a bit of internet browsing shows they can be referred to as a bell since they resonate the laser charge.

You are up Pliskin 

No not to easy. It's just  that the same place I worked with a water jet I also worked with lasers (cutting, welding, and heat treating). The largest was as big as a car. If I remember correctly it was a 5000 kilowatt. You might know what this is. I used a laser to cut these.
