I'm looking at possibly purchasing a 13-1/2" (13-1/4"?) Kalliope disk
music box with 10 bells.  It comes with 5 disks.  Does anyone know if
Barry Johnson makes disks for this size box?  Are the Kalliope bell box
disks totally different than the non-bell disks?  (In other words, are
they interchangeable?)

I tried to call Barry, but only get his answering machine, and may not
have enough time to wait for a "snail mail" response from him.  Thanks!
