I would like to find information on the music box maker Johann Heinrich
Heller, who lived from 1830 to 1906.  I am interested in seeing his
creations compiled in book form, from earliest to latest nearing the
end of his life.

  [ As a starting point, I suggest Arthur W.J.G. Ord-Hume's "The
  [ Musical Box: A Guide For Collectors, which write about Heller
  [ and some of his products.
