Bob Fitterman inquired about the maker of a music box.  I'm afraid with
the limited information that has been supplied, it would be impossible
to identify the manufacturer.  Typically this requires a name on the
mechanism, identification of the style of tune sheet, or occasionally
there are manufacturing characteristics that will identify a maker.
Many makers had the cited tune ("God Bless the Prince of Wales") on their
music boxes.
