I am surprised that no one had mentioned a visit to QRS Music Roll
Company on Niagara Street in Buffalo, NY.  They are close by and have
regular tours.  Alternatively, call and talk with Dan Wilke and see if he
can arrange a private tour.  Ann Jones of QRS is on the Internet and is a
subscriber to MMD.  You can send a note to her at <annj@qrsmusic.com>.

If you are in the area you don't want to miss a chance to visit the
largest and oldest remaining manufacturer of piano rolls.
