Hello all, I'm new to this forum.  For many years I have had
a Philipps DUCA reproducing piano.  I have restored it to a good
(but still not perfect) playing condition.  Thanks to Tom Jansen
from Monschau, Germany, I now have a test roll.

What I am still desperately searching for is a description to
adjust the reproducing system to factory specifications.  This is
essential to have it play as it did when new, now nearly 90 years
ago.  Any help would be really appreciated.
