All of these are hot and in-use - except for the Voltmeter.

That's really cool. A little nerve wracking, but cool.

480 volt nominal?

120/208

3 phase

The more that I think about it, this is as well made - most likely much better - than anything today. It is just missing a layer of grounded metal for safety.

It'll all work fine till the fuse holders loose their "spring" and you start to get heating at the connections, which causes the metal to get even more loose. 

The thing I love about equipment like that is the smell. There's always this great smell in those places.

I've noticed an oily smell when I'm near that sort of equipment.  I've a 480V, 3 phase motor starter, rated about 200 HP, in my shop that I took home from a job at a wax/lube oil plant.  It's likely much older than me.  We were installing new ones and I couldn't bear to throw the old one away.  The thing must weigh about 150, 200 lbs.
