Trev, it does appear Mr D' Eville cares less and less about his customers doesn't it? <img src="http://jsramsbottom.co.uk/bbs/e/icon_rolleyes.gif" alt="Roll Eyes" width="15" height="15"><!--graemlin:--> I contacted you a while ago about bits - are you supplying parts on a commercial basis (ie, if I pass folks your way will you track me down and kneecap me) or are you only working on favours?? I'm still thinking about improved hammer springs but I don't really want to just dump the situation in your lap, especially if you're not going to make a couple of honest quid out of it.
