Hi MMD,  At the recent AMICA convention in Buffalo, New York,
I watched Ray Dietz use a piano roll hole punch to repair rolls.
This is a superior means of repairing a roll where the punchings are
in need of repair.  Player Piano Co. has not carried these punches
in years and I've not been able to find any manufacturer of this
style of punch.  Does any reader know where one might be obtained, or
if you have one just laying around would you be willing to sell it?

Thanks,
Tom Hutchinson
