Dear friends,  I am the owner of a 44-key Gavioli organ with flutes
and piccolos, numbered 2049 and labeled:

  Gavioliflute, Gavioli & Cie, brevete S.G.D.G & patented,
  14 rue d'Aligre, Paris

This was Gavioli's first address in Paris.  The company moved to the
address 3 Rue de Citeaux, two blocks away, between 1862 and 1865, so
both Marc Kaufman's organ and mine must have been built before that
year.  My Gavioli organ has a cylinder marked with the Rue de Citeaux
address, so it must have been built between 1862, the year of the last
patent, and 1865.  Maybe it can help to establish when Marcs organ was
built.

My organ has 20 bottom pipes, of a very peculiar construction, meant
to imitate an orchestral flute.  I am preparing an article about it
in the next issue of "Het Pierement".  It will also appear in "Musiques
Mecaniques Vivantes", the journal of the French society AAIMM,
translated by Philippe Rouille.

I am very interested about details of both Marc's and Pierluigi's
instruments!  For the MMD Archives I have included some photos of
Gavioli #2049.

Regards from the Netherlands,

Hans van Oost
