THis leads me to conjecture that the other mfg'ers used internal piston and cup rather than plunger and compensator port valve. They would HAVE too due to the leveraged pedal arrangement.
Not according to Motors or Chiltons. The pictures are the same and depending on the car, those books just reference you to the particular section your unit is.
There were two types of BTV, the hydraulic reaction type (HRT) which looks the same but is quite different internally with the plunger being hollow & a membrane on the end pressing against a rod & actually feeding back info to the vacuum side and the poppet valve type (PVT) we use. Several cars used the HRT type but no BTV listed has a piston & cup. There were other Bendix units that did.
