"Never got round to sorting all your duplex London cancellations (incl. District and Branch Offices)? Kept them loose or in little stamp-bags? On stamps (or with cheap stamps on postcards/letters or on entires)? Or maybe you are tired of them in general? HERE IS YOUR HELP (FROM GERMANY)! I am interested in those stamps or items and would refund you at least twice the price you have to pay for postage (and if I find some missing from my collection, I'd pay a little bit more by PayPal to a friend).
