Neil,

Maybe a long shot, but why don't you give these two guys a try?

Steve Pope, V-Mach. Although the main thrust of his business now is tuning kits, custom parts, beautiful custom rifles etc., he also very often has some second hand bits knocking around.

Dave Welham of Airmasters 88. In the early days of FT, Dave really campaigned the FWB as opposed to Venom endorsing the HWs. He tuned lots of these. So, yes, long shot, but maybe worth a call?

It's not like anyone's come running to your rescue in a while.......
