Wow thanks for each of your replies and advice. Much appreciated.
Both Hilary Stone and Singlespeed Components think they have stock that will fit and advise I need a hex nut fitting calliper. Like you've all said I just need to measure the drop correctly. All the hex nut callipers I've seen so far (mostly ebay) are strangely long drop but I think my frame is standard drop but I'll do an accurate measurement based on Sheldon or Hilary's measuring guide.
My spares box is filling up nicely with stuff I am buying twice!!
