Hallo Wolfgang!  You wrote in Mechanical Music Digest (01.07.29):
> ... anyone of you knows of recordings with organ-music?

Maybe you will make a find at

  Oesterreichische Mediathek des Technischen Museums Wien,
  http://www.mediathek.ac.at/

The web sites are in German but English readers will also
find useful links (Austria + International) at
http://www.mediathek.ac.at/Links.htm

They have a gigantic collection of old media, that are not even
partially refurbished.  I don't know whether anything is sold, however.

And here you might also find something:

  Mechanical Musical Instruments from the collections of the
  Phonogrammarchiv of the "Austrian Academy of Sciences"
can be found at http://www.kfs.oeaw.ac.at/dli/mech/dlidem1.htm

Incidentally, member Helmut Kowar is also a member of MMD.

Oesterreichische Mediathek has also one of the two laser phonographs
which exist world-wide.  It is hand-made by a Japanese man; I vaguely
remember that the cost was between 50,000-100,000 USD.  All the old
shellac recordings can be tracked without mechanical contact, thus the
condition of the discs will not suffer.  (I've heard that after some
dozens of normal playing a shellac disc will be worn down).

When it comes to old and historical recordings this collection can
also be a source for information:

  Phonogrammarchiv
  The Austrian Research Sound Archive
  http://www.pha.oeaw.ac.at/

Servus!

PS:  A new search machine for on-line articles in German is available
at http://www.pressechef.de/  At the moment there are more than 30,000
contributions available.  Although the possibilities of a combined
search with Boolean expressions are missing, it's still very usable.  :-)
