Wanted working early brake servo

[spanneredmonkey]

I have found out my servo is probably lunched, and a good chance the master cylinder along with it I cant stretch to a new one at the moment was wondering if anyone had a working one they would part with for sensible money,

I've got a MC from my bus which I believe to be fine. Only reason I replaced it was because I went to narrow 5 so everything else was new.
