Terry, I don't know anyone with a workshop who'd be prepared to, and I don't have the skills.
I'm never certain when Molly's going to be anywhere and I need advance notice before paying out more than about a fiver for anything... and I've only two training weekends left (that I can get to) while I'm a junior, so I suspect that's out...
Allancet, as you've only two I'd like to know if they've the same threading as my stand does, how often do you get to Bisley? Or are in Hampshire/Sussex area? If so then... well I'll work out a price later, but I can pay you then if they do fit.
