If anyone is interested, I have a technical drawing of an adaptor that makes it possible to fit a BMW master cylinder to a metro servo.
A nice chap at work did it on Autodesk and a local engineering firm produced it and it works brilliantly.
It even includes a groove for a BMW 'O' ring (which is needed to maintain vacuum. I think that someone asked if that was important in an earlier thread).
The only thing I had to do is to shim the servo pushrod.
It also gives me a nice shiny bit to polish in the engine bay.

Quick pic to show the shininess.hoto:

Looks nice, a bit more hardcore than the one Marlin supply, also with the Marlin one you need to make an extra adapter:
