Does anyone know anything about the origins of the original Josette's music-box on the original series?  Was it custom made for the show?  Did the prop department buy it somewhere?  Did they have more than one on-hand, in case it got broken?  What was it made of?  Was it some kind of antique? Was it really a music-box, or did it have some other function?  Has anyone seen anything even close anywhere else (aside from the plastic replicas)? 

I've always been curious about the music-box.  Just wondering if anyone has any information about it.
