Tiny Mechanical Teeth!

I have around 100 music boxes in my collection and most of them are mechanical, because I prefer those to the ones with electronic chips in them.  As far as I know, this is the only one I have that no longer plays, because it is missing crucial parts.  One thing it still has is the wheel with the tiny teeth that would pluck the metal "keys" to play the tune, so this is my Tiny Tuesday entry for the "Mechanical" challenge.  Thanks to HOtamer and Hanulli for hosting......
