Hi, I was looking at some entries on the 2nd or 3rd page of the Vintage Machine list (this one), looking for featherweight articles, and came across someone called Texasgal ? I think that was the name, but couldn't find it on google. Anyway, she had a lot of featherweight parts (although not the one I wanted, which is why I didn't bookmark it). So have a look at some of the earlier entries and you should pick it up. Sorry I can't give you the exact details.
cheers
