On page 231 in the book, "The Music Box Makers of St. Croix," by Piguet:

  At the beginning of the 1940s, after having worked for Lador in
St-Croix, Louis Jaccard-Bahon took over the mechanical workshop of his
father Jules, who made combs and other supplies for small music boxes.

  On Feb. 18, 1944 he applied for a Swiss patent to make cylinders cast
in one piece with one injection-molded end.  Along the same lines, he
developed a multiple-cutter machining-tool to slice the combs of the
music boxes and again applied for a patent on Dec. 11th.

  The following year, he submitted three patent applications one after
another for a speed regulator for small music boxes; for a ratchet
wheel and for a 'bedplate cast in a clamped mold forming a single block
with the two cylinder bearings, the spring housing and all the elements
activating the speed governor.'

  On Feb. 6th, 1951, he modified the name of his company and adopted
the name JALCO, with the objective of manufacturing musical movements,
doing lathe work, etc.  Business flourished to such an extent that he
was obliged to build a factory to accommodate machines and staff.  The
building was transformed into lofts, which still exist today.

  In the years 1953 and 1954 he took part in inter-factory negotiations
to fix minimum prices.

  In 1963, Louis Jaccard-Bahon was still among the ten music box
manufacturers in the region but business was depressed and so he
decided to transfer his company to Jean-Paul Thorens.  On Dec. 17th,
1963, the buildings and machinery were sold, but the sound of music
boxes continued to tinkle inside the factory.  A few years later
Louis Jaccard-Bahon died in an accident in St. Croix and his company
was struck off the register on Dec. 19th, 1969.

The above has some paragraphs left out, but that is the gist of
information on that particular maker.  The book can be purchased
through me for $40 + postage ($5.00 USPS Media Mail or $14.50 Priority
Mail) _or_ through the Musical Box Society, Intl.  All proceeds from
sales through me go directly to MBSI.  It's a great book on the more
modern makers and probably the only source of information extant for
such information.  Enjoy!
