My guess is that they were all F1264x (x being the 2, 3 or 1 right?). If they had the F on them it means they were made specially for the factory (i.e. never carried in a boutique) and sometimes it is really hard to find pics or information on those bags unless someone is selling one on eBay. Did they have an F in front of the second set of numbers, like this XXXX-FXXXXX ?
