hello, I'm looking to sell an old much loved but unused filofax. I can't find any to compare with, so hopped you might be able to help. its a 2007 soft jade A5 finchley, it is missing the diary insert but has everything else it came with, is unused, and still in the original box. I don't expect you to know the value of all filofaxes, but might you point me in the right direction? Thank you!!!
