Just in case it would be helpful to you to have more pictures of organs
by Ignatius Blasius Bruder, I send a JPEG-file of the instrument in the
Utrecht Museum "van Speelklok tot Pierement".

The organ was built about 1830.  It has 25 keys: three for the
figures and twenty-two for the notes: c-g--b-e3 diatonic, with f#1
and f#2 added.  The conjurer behind the table changes the objects on
the table between bird, apple, die, and nothing.

Like Mr. Brommer, I am very curious if such instruments are known
outside Europe.
