Claire, are you perhaps referring to the "Refugee Section"? That little heap of more-or-less collapsed Ukrainian Leitz copies?

They came to me by chance - I was after ONE, then discovered that what with postage, popularity and so on it was cheaper to buy 10 from a new seller without feedback... So I did - I have managed to find some of the better ones new homes, but the rest are huddling together in the bottom left corner of my cabinet
