Bette is welcome to ask anything specific about Ruth organs.  Mr. Jan
van Dinteren, member of the KDV committee, has published lots of
historical information about the Ruth factory, their production, and
music.  Mr. Hans Brink, a devoted KDV-member, a personal friend of mine,
and a fine restaurator of German and French fair organs, has published a
lot of technical articles in our magazine, "het Pierement".  All those
are in Dutch.  I could translate parts that might be interesting to her.
Please contact me if necessary.

Hans van Oost, KDV, Holland
