I just happened to read that Brian Chesters was looking for additional
Polyphon 11-1/4" bell disks.

At the time that I purchased my Polyphon bell machine it came with
only one disk.  As time went by, additional disks surfaced, and Barry
Johnson in Mountain View CA (USA) now offers 16 tunes available in this
size.  I'm delighted to have this much music available to play on my
bell box.  Original disks of this variety are virtually impossible to
find.
