I was asked for the trackerbar layout of the Kuhl & Klatt pianos.  The
music rolls, made by Bacigalupo´s "Exelsior Notenrollenfabrik" in Berlin,
bear the trademark "Pneuma" and are cut with square holes.  A picture
of the spool ends is at http://www.maesto.com/US/kuhl-klattus.html

Kuhl & Klatt instruments are quite underestimated, but if restored
properly they produce fantastic music.  Almost nobody knows that Gustav
Bruder(!) made several arrangements for Kuhl & Klatt.  Most of the
pianos are equipped with a reiterating pneumatically operated mandolin.
Some have a xylophone in the top.  They have a wooden tracker bar.

Kuhl & Klatt roll (Pneuma)
  Width of paper:  340 mm [13-3/8 inch]
