Not sure if I can be of assistance, but I have a fledgling workshop in
Rome near Piazza Navona at Antichita Tanca.  Otherwise, Michel Bourgoz
in L'Auberson, Switzerland, naturally does flawless work.

I was there in L'Auberson last winter to get things going and work for
a lovely client, Milena Tanca, who has specialized in musical boxes,
the Piano Melodico and automatic musical instruments and a general line
for forty years or so.  The Tanca family are the oldest antique dealers
in Rome.  Just before I left, I hastily taped a few spontaneous clips
of Antichita Tanca for a YouTube posting.

There are almost no collectors in Italy but I'm gathering information
and chatting some folks about continuing my work there.  It's not so
easy learning a new language as well but it's quite necessary.  Just
before I left, Antonio Latanza, the director of the National Museum of
Musical Instruments, had me pick up a 66 cm Adler upright music box
that a previous man had butchered fairly badly.

In Longiano last March I visited Franco Severi, the director of AMMI
[the Italian mechanical music society].  He said there are always
blustery types who profess skill but that he knows of no qualified
restorers of musical boxes in Italy.  Apparently he refers all
inquiries to Switzerland at this point, but he was quite enthusiastic
about working together once I could give firm details of when I would
actually be in Italy.

I would be very interested in finding any original information written
in Italian about musical boxes or related matters.
