Piano Roll Compatibility & Roll Types

Hi All,  It's most likely that Autograph and QRS rolls will work in
a 1933 Triumph player piano.  However, the term "about 11-1/2 inches"
just isn't accurate enough.  The paper used to make all 88-note player
piano rolls is 11-1/4 inches wide.  I'm not sure if Autograph or QRS
ever made 65-note rolls...

In order to avoid the confusion that can occur by saying that a
particular manufacturer's roll will work on a player piano, it's
best to determine whether or not the trackerbar in the instrument
is a standard 88-note type or a 65-note type and whether or not the
mechanism has the correct roll chuck.  To help people figure this out
for themselves, I wrote a web page some years ago.  It's located at
http://www.player-care.com/rolltypes.html

This is one of those cases where a picture is worth many, many
words!

Musically,
