Strange you should ask that but a new 404 appeared in WMT last week: for the 2004 product catalogue that was on the site Nov 2003 to Jan 2005 or thereabouts. Lists a dozen backlinks for it too, most of which haven't existed for 5 or 6 years or more (didn't check the last two listed sites as they are spammy sites I would never visit).
