I don't know, to my shame.  Yes, I held it in my hands and photographed it.
КДВ2 But already sold for silver.  I think the mounting brackets are the contacts.
There is no electromagnet, mechanical drive. Used in electrical substations.

stivep,

Looks like a outlet box you can buy from Lowes or Home Depot, simple relay box I can make for pennies and sell it to you for $450.00

LOL

It is a vacuum relay. Never used, certified, military grade.
The original price for it per piece , was around $6800  "on that money" in 1990-
I'll  keep it  to build more powerful device I have.

I think such monsters will be difficult to handle.
Normal small vacuum relays, more suitable for those described in the first message:

Relay data:

It is not clear what function the relay should perform. If it is necessary to create many pulses  60 Hz with a mechanical switch, then you can look at such ancient devices:

But this devices mostly are for very low switching power.

Russ mentioned small engine
3-4000 rpm ( cycle speed of relay contacts


High voltage (car ignition ...maybe higher voltage "plasma" as per some water fuel claims ?
Nothing there that should not be impossible to find in vacuum relay ( double solenoid? Perhaps exotic metal on contacts?
Interesting if this component is make or break on it working?
