A silly idea I know, but I wonder if anyone has ever plotted all the locations that are used as Filofax Organiser model names on a map?
Such as in: Eton, Finchley, Finsbury, Guildford, Kendal, Lyndhurst, Winchester etc
To get you started I've put the above locations on a Google Map, you should be able to add other locations.
I know people plan pub crawls around the London Underground using Google Maps... but a Filofax tour... that would be different!!
