66 Dart GT HT Whatsitgonnabe?

Here are a couple of pictures of my master cylinder. I've pulled it apart and right now I'm considering using it. Either with the VW brake booster that's mounted in the car or w/o brake booster.

Thing is, I'd like to know if the master cylinder is for PB or manual brakes.

I think the previous owner said it used to have PB but that the brake booster was leaking and he couldn't find a replacement booster which is why he installed the VW booster. He figured it would be easier to maintain a VW solution in Europe. Spare parts availability, metric fittings, etc.

edit: can't get the links to work. Posting pics directly in stead. :protest:
