I went to put a seal kit in my master cylinder at the weekend, only to find it was a right old mess (full of rust, a decent lip preventing easy removal of the pistons etc

Do any of you have the MK2 Escort master cylinder lying around if you have changed to a bias pedal box? Ideally I'm after a 19.05mm bore one, the casting marks on mine are Girling 74660038 Q105, but I am struggling to find any reference to this so I'm 100% of the original application. It has two ports pointing towards the drivers side and one pointing down.
Any help would be much appreciated as I'm supposed to be away in it next weekend!
Cheers,
Craig
