This is snakewood (for those of you who don't recognize it). The blank has been around for quite some time (Thanks, Bill B!) and has been in the low humidity of the Arizona desert and the high humidity of the DC area in August. Who knows if that will be enough to keep it from cracking.
Thanks to all who look and particularly to those of you who wish to comment.
