I found the valve I was after for an MFI toilet from Siamp (based in manchester) via the cisternspares link above. I know this is an old post but thought this bit of info would be useful for others also.

Look up in directory local plubming shops [if you haven't tried already] ring and ask them. I assume MFI was as useful as a chocolate tea pot.
