This probably isn't much use, as it's from 1996, but at least it's a list to start crossing off. Thanks to W.J Markerink, a link to a page on his site;

Incidentally, Process Supplies in London have a vast quantity of Fuji duping film in 70mm. All out of date, but only a few pounds a 30m roll. I can't find it on their site, but I'm sure they still have plenty.
