Thanks to Jack Kane and Larry Greenfield for suggestions regarding a
source of discs for my Kalliope Music Box.  Renaissance Discs has
twenty discs available in the 52 cm (20-1/2") size.  They advised that
they have reproduction discs available for many different disc music
boxes, including a number of rare machines.  A list is available.
