I have been collecting music boxes for many years.  I just love them.
Recently, I was given a strange little music box.  It is inside a clear
container, and I can see the musical pieces inside.  It's so small it
sits directly in the palm of my hand.

It does not look updated.  It looks vintage.  On the bottom, it reads
"Die Forelle".  What does this mean?

It has the engravement MAPSA on it, then Switzerland.  Swiss Musical
Movement.

Thanks.  Please provide any information.
