It may have come from a BMW site, but its still an old Girling mcyl design, (TV/CV = Tipping valve/Centre valve), as used on the early Ford Escort
(Mk1). And possibly on the Mk2 also (I think!).

This one was used with servo booster, as you can see from where the mounting flange is positioned. Its clearly a non-simco (non-simultaneous cut-off)
type, and was used for F/R split brake systems. Used on older model Mercs.

Smaller rear drumbrake cylinders will work.
The Girling one's come in 17.8, 19.05, 20.64, 22.2 diameters.
I have M16 front calipers and 8" rear drumbrakes with 22.2mm wheel cylinders.
Me too, although I also fitted a PCRV (pressure-concious reducing valve) in the rear brake circuit. Another suitable valve could be one from an
earlier Fiesta (not sure which vintage). These were fitted into the Fiesta mcyl outlet ports.

I've seen those pictures before, just never actually seen one.
However I'm not conviced how they work. Bear with me as I don't think it's actually as obvious as it first seems.
Smaller cylinder creates more presure than a larger... but in this case, the secondary piston is floating so the presure either side should be
equalised.
