Chess Board 40x40cm (or close-ish) (Abingdon OX14)

In the spirit of "if you don't ask, you don't get" ... does anyone have a decent quality wooden 40x40cm (or thereabouts) chessboard that is unused and looking for a new home? We have large pieces for our disproportionately small board, and now my son's getting more serious about chess, I'm wanting to get a board which matches our pieces.
