I am seeking original QRS roll information. On page 168 of the
"Player Piano Treasury", by Harvey Roehl, there is a reproduction
of a QRS advertisement which touts the superiority of QRS rolls over
other rolls. The text of the ad reads, "Consequently whether or not
your player pedals easily depends largely upon the kind of player
roll you use."
It further goes on to say, "There is a real scientific reason why QRS
Player Rolls make pedaling easier. The reason is fully set forth in
a folder sent gladly at your request."
Has anyone ever seen this folder, or have one which they would make
available for copying? I think it would be quite interesting.
