Nice! I also had such an big automatic voltage regulator some time ago.
"Problem" is: I don't remember how it works but the variac itself (which
would be interesting for TC use) is only a relatively small one, maybe 10kVA
or less. The main power (75kVA in your case) comes from the big standard
3-phase transformer, which is controlled via the small variac + controll
transformer.
Maybe you should add an info to your auction, that this is NOT a 75kVA
variac, this could lead to some confusion and you could get some trouble
otherwise :-)

Subject: [TCML] Giant Variac For Sale
If anyone is interested in a massive 6-stack variac, we have one for sale.
http://www.ebay.com/itm/222067908245
This happens to also include a solid cabinet with a large transformer and
some control circuitry. The unit actually works, but who cares, it's a
giant 6-stack variac :)
And a matching massive switch as well
