I have just acquired an 8-rank Kilgen Residence pipe organ, with a
4-roll player.  The tracker scale is described in Bowers & Reblitz
(Treasures of Mechanical Music) on page 411.  Alas, the test rolls which
were presumably in existance in 1981 can no longer be found.

I would appreciate any information on Kilgen organs, and on
Roesler-Hunholz Concert Organ rolls.

The organ was removed from its original installation about 6 years ago,
and needs extensive rebuilding (every piece of leather has decayed or
been eaten by rodents).  I'll keep the group informed about the progress
of the restoration, which ought to be fun, if tedious.
