Hi Craig,  I just read your posting in MMD 060412.  Unfortunately,
I do not have an organ clock made by Dufner, but I have the books
you are looking for.

"Flötenuhren Aus Dem Schwarzwald" by Holzhey, Günther, is a small
booklet and it would not be a problem at all to scan it and to email
you the images.  Could you read all the German text or would you be
interested only in the pictures?  Please feel free to tell me what
you would like to get -- I will make it.

I also have "Figuren-Drehorgeln von Ignaz Bruder und seinen Nachkommen",
ISBN 3-7806-7240-5.  This book is too big (140 pages) to make a full
copy.  Would you be interested in copies of specific pictures out of
this book?

There is another most interesting book, by Herbert Jüttemann, which you
did not mention: "Schwarzwälder Flötenuhren -- Kostbarkeiten aus der
frühen Uhrenindustrie des Schwarzwaldes", 1991, Waldkircher Verlag.

The copy I own shows no ISBN number.  This book shows many details of
flute clocks, only one picture of a Duffner clock (Sigmund Duffner)
without automata, a genealogy of the Black Forest Flute Makers.

Let me know whether you would like to get some copies, I will email
them to you.

Regards from Germany,
Christian Greinacher

 [  Herbert Jüttemann: Black Forest Flute-clocks.
 [  184 pages, with 16 color plates, many drawings and pictures, bound.
 [  ISBN 3-7806-7236-7
 [  Treasures from the early clock industry of the Black Forest, in
 [  historic and folkloristic viewpoint, and their technology.  The Black
 [  Forest flute-clocks, that essentially originated in the period from
 [  1790 to 1840, served [the customer's] lofty pretensions.  Their
 [  melodies amuse our nature and their colorful fronts, often equipped
 [  with movable figures, please our eye.  They surely belong to the
 [  most beautiful Black Forest clocks.
