Have you seen this piece?

And now for the back of the milk carton edition of BCC Weblog...

Adam Fletcher is looking for our help in tracking down a piece from a rare chess set:

Would it be possible for you to ask the blog readers if they could help a friend of mine find a black bishop for a rare chess board? The board is a hand-made set from England, from a gallery in Hull called Studio Anne Carlton. The set is themed around revelation and only a short run of them have been made. The gallery is out of business as far as he knows....
The missing piece is the black bishop... It's a beautiful set and it's a shame it is not complete.

Here is a gallery of pictures of the set. Can anyone help out?
