I will be attending the Mechanical Music Mart in Ruedesheim again,
with a new selection of antique music boxes to sell.  One is a small
keywound box with exposed levers and plays 4 airs, including the
French national anthem.  It has the serial number 5574 and the
initials underneath are "PHP".  I don't know a maker from 1830 with
the initials "PHP".  Any ideas?
