68 valiant with disc brakes and leaking Booster

hello everyone. I have a 68 Valiant and the previous owner converted the front brakes to power disc. Now we have a leaking Booster, but I can't tell who the manufacturer is for the master and booster assy. Is there a way to tell if it's Bendix, Kelsey, or Budd? Or even more, does it matter which one if you may plan on swapping out both the master and booster all in one shot?

Yep,post a pic

Hopefully these help to determine what type booster this is. if not, I can get some more when I get home from work.
