The Stéréo Alain was produced in France in the early 1950's and is
constructed from plastic. As with many French stereo viewers this one
was sold at Lourdes and many of the film subject titles are of that
area.
The viewer used roll film that was
fed into the top of the viewer and then manually pulled down through the
viewer. A common problem with these viewers is that the light diffuser material deteriorates with age and takes on a
rippled look. The diffuser must be in good condition for this viewer to
retain it's value. The packaging used by the Stereo Alain looks very similar to
that of the
Célde viewer, also manufactured in
France and this may possibly suggest a link between the two brands.
