There were different note ranges for the xylophone in A-roll pianos.
One example would be that Seeburg, without exception, used a 22-note
xylophone in their A-roll model pianos, and Seeburg used the same
xylophone in the KT and E Special models that played the G roll.  The
Seeburg H used a different note range.

The Seeburg xylophone plays from G up to E.  The notes above E are not
played by the xylophone but early Seeburgs with pipes did have 25 pipes
to play these top notes.  No one knows why Seeburg cut out the top
three notes in xylophone models.

To add more confusion to this note is that the K models play the music
in a different key than the keyboard models play in.  The actual note
range of the A roll is from bass C to high A (58 notes) but the K model
plays the highest note as a G, one whole step flat to the keyboard
model or the actual roll scale.  Nelson-Wiggen also cut out the top
notes in some of their models.

The Coinola models used a 24-note xylophone (from A-sharp up to A) in
their models, with the exception of the Coinola Cupid with xylophone
that is so rare only one is known and I have lost track of it.  Coinola
also made a Cupid with pipes that is very rare.

So the answer to the question, "What was the note range of the xylophone
in an A roll piano," depends on the maker of the piano.  If you are
rebuilding one then look closely because there were no rules.

The xylophone in the Seeburg that was previously mentioned was added by
a restorer in the 1970's which explains the 24-note range.
