Hello!  We have a 13" cylinder music box and we can find no mark or
serial number.  It has 8 intricately composed tunes.  The only 'unique'
identifiers might be the zither attachment that is a screw and not
a lever, and the tune numbers stamped on the teeth of the gear that
actuates the cylinder shift.

I've attached photos.  Any help would be much obliged.
