Brake Master Cylinder Identification

[1966marden]

Can anyone tell me the make and part number of the standard, Caterham fitted, Brake Master Cylinder on my 1996 Superseven with 1700 X Flow engine. I am told they are a Girling item, and very expensive from Caterham, but are they fitted to other vehicles and therefore available from other outlets at more reasonable cost? I have an e-image if that helps, to post to somebody for identification. Thanks!
