Does anyone know of a source for the piston seals and oil seal on the ATE servo's on my 3.0 CSL? The ATE reference number is T50/29/33.

I spoke to Nelson (based at Highfield Road, Camelford, Cornwall PL32 9RA) and they asked me to send the seals I had and they'd see what they could supply.
They were able to provide the hydraulic seals - the two for the air valve piston (both identical) and the two for the main bore. The part numbers they quoted on the invoice were S9429 (air valve 2x2) and 2 of each of S9450 and S9619 for the main bore.
There's another seal at the vacuum chamber end - it transpires its the same as the servo seal used in Mercedes servos and is also the same as the throttle body on the 600 - these came from Niemoller - I had to buy 4 of these as there was a minimum order, so I have 2 spares! Part number on my invoice is D 08 175, described as a B8x16 DIN6503 sealing ring
The bodies were resleeved by Past Parts.
There is also a thin O ring, a fairly generic part I think, and finally the seal for the end of the vacuum chamber - I reused mine, but I guess there would be a source somewhere.
