I saw this on ebay and I think it might be another way to add power brakes to Studes and others. These are used on Lexus hybrid SUVs. I don't see any connection to Antilock, just 12V. Might even be able to do it under the floor. Would need 12V and under floor would need remote reservoir.

I was looking on alldata and it looks like that cylinder thing below the master cylinder is called a brake stroke simulator and it plugs into an abs/skid control module so it probably won't work without it.

One of the large "Internet/Mail Order" brake system suppliers advertised an electric booster for around $1,000 - And, no I do not recall which supplier (last year it was advertised in many of the car magazines).

Here is a quick search for a electric brake booster for much cheaper from many sources.
The expensive one must be from Speedway they seem to have one for like $1300

These are not brake boosters, they are vacume pumps that are used to provide adequate vacume for a vacume brake booster.

A better idea...just use the proper sized master cylinder.

I've driven two and am building another Stude (brand has no bearing) with either disc-drum, or disc-disc, and used no big heavy, space wasting, ugly power booster. The disc-drum car was pretty much a normal stopping car, while the disc-disc car is a two toe stopping car.
The floor mounted pedal length is just right, and I assume that the hanging pedals are very close in length to having a good lever arm length.

Do a little homework and save money and space, just get the right sized master cylinder for the calipers you are using.
