Pics of my auction purchase.
Discussion
As Andy and Joe advised, I checked the bottom of my servo and unsurprisingly the top is shiny but the bottom don't look so good. Joe recommended a servo, but is this a direct replacement and will my existing master cylinder fit on it? If not, can anybody recommend one that hitches on without the chopping about?
This is the one I bought off eBay a few years ago...

... and the m/cyl is wrong, but the vacuum take-off hole and m/cyl studs look like they are in the right place. For that money it would be worth checking out maybe? Worth a punt for less than 20 quid I'd say.The seller accepts returns so all you'd be risking is the return postage.

Just a slight word of warning, that unit may well be a very good find but please check the INTERNAL dimensions. There are quite a few servos with the same casing but you need to check carefully
firstly that the operating rod for the master cylinder is the same and has exactly the same displacement from the master cylinder mounting flange. (there may be a small adjuster which will enable you to get the tiny clearance necessary to ensure the servo isnt deflecting the master cylinder piston when you are not applying the brakes.
secondly that the operating rod at the pedal end has the same displacement as your original. This rod should be fixed. If the rod is a different length it will change the pedal travel and a small difference at the rod makes a big difference at the pedal. There are some with a shorter rod which wont give enough master cylinder deflection within the comfortable travel of the pedal.
You may also find the clevis pin hole is a different diameter (most likely larger) than the original which would require drilling the pedal and fitting a larger pin. It may also need shim washers if the clevis is wider than the pedal. And it should be a hardened clevis pin not any old bolt. That isnt an engineering problem provided the first two points are OK.
(when the research was done into alternative servos some years ago we were surprised by the number of variations in servos which superficially looked very similar)
Playing with the brakes obviously needs a lot of CAUTION. Finding out that you cannot quite get full cylinder depression when approaching an obstacle at full speed is not the time to find a problem. Apart from insurance issues we dont want to see any S cars lost! (Oh, not too keen on S drivers being lost either!)

May be a job for my trusted mechanic then.
