I believe this is the board that had the glass stain mentioned in the introduction.  It may have been stored in a shed for years, because it had some mold sometime in its life near one lower corner.  The ends show the results of the mold, but be assured they were sanded until it was completely gone, and the oil finish now makes the surfaces equal to any of the other boards.  The top has one tiny indent.  The wood is probably Spruce.  174 mm.
