<DIV><FONT face=Arial size=2>That's my aim (and what I did), =
Jon. I
replaced the blue and green front rail paper =

whatever
few paper punchings I needed to make the dip right. I think I now =
may have
almost a lifetime supply of blue and green front rail punchings just =
from what I
took out of this piano. :-) I wish I had had my camera =

me--the stacks of blue and green were stunning.</FONT></DIV>
