Greetings to all;  In the current issue of "Carousel Organ", The
Journal of COAA, there is an excellent article on Oscar and Leonard
Grymonprez.  It is of special interest to us as we purchased a 72-key
Fr. Decap, Herentals, dance hall organ in the early 1970s from Leonard.
We were put in touch with him through Marion Roehl.

The article was also very timely as we recently began to do some
work on the organ and have several questions.  Is there a standard
or typical layout ('tracker scale') for the 72-key frame?  We are
finding some discrepancies between the tune book and the way the organ
is tubed.  The tune book has had some revisions in the past, so we
cannot help but wonder if there is standard or such.

Any help anyone can offer will be greatly appreciated.

Thank you,
Bob Oppenheim
