I've just received the following e-mail from Felix Thorn --

  Hello,  I am looking for a set of miniature music box combs with
  a full octave of notes.  It appears that most small music boxes
  include only the notes used in the piece of music on the cylinder.
  I am building a piece of art and need around 20 of these combs.
  Do you have anything like this or know anyone else who does?

  Regards,
  Felix Thorn

My only suggestions are that he either buys 20 small hand turned
movements and re-tunes the combs, or tries to find someone who can
make new combs for him, which might be expensive.  Does anyone have
other ideas?  (Have a look at his web site -- interesting.)
