It’s on a 1941 GMC CCKW. It has a master cylinder under the cab and has a hydrovac unit on the frame rail behiend the cab. It has two valves in it to take vacuum from the motor and vent it. it also has a tank to build pressure in. It’s to have increased line pressure to stop the truck being that it weighs 10,000 lbs.
