Nancy Fratti, Canastota, New York, has over 1500 music box discs in
stock. She offers a list for $4.00 or welcomes specific requests by
email: firstname.lastname@example.org [delete ".geentroep" to reply]
Barry Johnson, Menlo Park, Calif., makes new discs for Polyphons and
a dozen other machines. Barry seems to be one of those Luddites --
luckily a diminishing group -- who doesn't have email. His phone
number is 1-650-323-5268.
Kevin McElhone <email@example.com> is in England,
but he ships worldwide and has discs for various boxes.
There are doubtless others selling discs, but these are the three
I can think of at the moment.
