Dear Victoria,  two years ago I had a phone call with MAP S.A. (MAPSA).
It is a small company in the southwest of Switzerland.  In that part of
Switzerland people speak French.  It was hard to find a person which
could speak German or English.

In that time they didn't have an Internet connection.  They are
producing 12-, 18-, 22- and 28- and 36-note cylinder movements and
musical boxes.  (Maybe they are still in business).

The address:

  MAP S.A.
  Champs-Lovats 30
  1400 Yverdon-Les-Bains
  Switzerland
  Phone: Switzerland - 24 - 425 66 36
  Fax:   Switzerland - 24 - 425 72 22

By the way: "Die Forelle" is the song title in German; in English it's
"The Trout".

Kind regards from
Hauke Marxsen, Germany
