Master cylinder in trunk??
 
A 57 Chevy on ebay. How exactly does this work?

I would assume a hydraulic coupling of master/slave cylinders, similar to a hydraulic clutch linkage. Look between the booster and the battery, you'll see what looks like a hydraulic cylinder.

My biggest worry would be trying to carry engine vacuum all the way back there.

Yup. More than likely he has a small single cylinder under the dash attached to his brake pedal that runs a hydraulic line back to the trunk to activate the dual master cylinder.

And then he has to plumb a vacuum line back there from the engine.

The things we will do for a clean firewall. :_paranoid

I wonder what the dipstick in the trunk is for? Did it have IRS?

Corvette suspension.
Crazy looking tube chassis.
The funny thing is there is still a master cyl on the firewall. I assume it is for hydraulic clutch.

It's probably an unboosted master that is running the slave in the trunk.
That's a complex mess of brakes for no apparent reason.

I don't see a clutch linkage of any type. I'd assume it's an automatic.

What a waste of effort - time - and money.

Put a good properly sized Wilwood manual M/C either under the dash using the Kugel 90* set up like I have on my '32 Ford -- or hang it on the firewall...

Looks to me like he was trying to get power brakes without having the ugly booster in the engine room -- but a properly set up brake system doesn't need a booster of any kind. A booster is a bandaid for improperly set up brakes.
