Could anybody give me some more information about a music playing film
projector which I have never seen before.  It is a metallic box with
a crank and an optical system.  This projector, obviously a children's
toy, is signed with a label:

  CINE RAI
  PATENDADO

The film strip, a strong semi-translucent paper, contains two tracks of
coloured printed pictures plus 15 lines of punched notes which control
the airstream to 15 brass reeds.  When the crank is turned, the "film"
is moved through the optics, a shutter gives alternating light (coming
from an electric bulb inside the projector) through either one of the
two picture tracks, so some movement of the pictures gets projected.

A bellows pumps wind into the magazine bellows and the perforations on
the film strip act as valves for the wind through the reeds.  On the
magazine bellows a serial number 39076 is printed.  Even after all my
best efforts in restoring the pneumatic system, the music sounds very
weak and soft.

Who knows about this toy?  Where and when was it produced?  Could it
sound and project pictures in a more acceptable quality?  Are there
film/music rolls available?  I would appreciate any input.
