Brake master cylinder I bought a while back from VWH, but will never use. This is for busses with a brake servo. Made in Brazil by Varga, As New condition, piston moves freely. Intended for LHD busses (I don't think RHD are available), so will likely need a small mod to one of the outlet pipes. Does not come with reservoir grommets or switch, but can be swapped from old cylinder. £40 posted.
Get your servo fitted and you won't care. The stock flexi's are fine...or are you taking up bus racing?
Don't need to change the master cylinder for a remote servo, so the above is surplus to requirements.
