You may want to check with a local large piano dealer, since dealers are
constantly needing good quality piano moving boards.  I work regularly
with a dealer here in Las Vegas who probably stocks about 40+ moving
boards.  Several are in daily use on the truck and many others are under
pianos in storage.  I have a few of their boards in my shop right now
from previous transactions.  They are in constant demand.  Chances are
good a dealer would be happy to acquire your board.
