I purchased one of the ebay UK ones last night, I have two, one that is in pretty good condition & one that's a paperweight, but the one that is in good condition has been turned into a wall plaque with some kind of resin/enamel molded to the back side. I was just afraid of damaging it when taking it apart so it might have to stay as a book end.
I'm half tempted to commission a run of them if they aren't readily available.
Cheers,
Quentin
