In response to Emily Kingsley's question, the museum you visited in the
past was the 'Henri Triquet' museum.  It closed more than ten years ago
and the collection was sold to a Belgian collector.  This weekend, a
part of this collection comes to auction at Galerie de Chartres.

In Paris you have no more a specific place with only mechanical music
instruments, but there are two interesting places to visit: Le Musée
d'art forain ( http://www.arts-forains.com/ ) and the Phono Muséum
Paris ( http://phonomuseum.fr/ ).
