Below is an English translation of the Table of Contents (das
Inhaltsverzeichnis) of the book by Peter Hagmann.  Ref. page 5 & 6 of
the PDF document at http://www.freidok.uni-freiburg.de/volltexte/608/

Fans of the big Welte Philharmonic player organ will enjoy perusing
the appendix (der Anhang) for the sketches and descriptions of existent
Philharmonic organs around the world.  Also included are drawings of
the pneumatic T-100 and T-98 Welte-Mignon piano systems.

Thanks to Matthew Caulfield for his help with this translation.  I can
always count on him to offer clear exposition and logical presentation.
