  Along the same line its interesting that the quality of
Schneider lenses changed completely after WW-2. Before the
war Schneider was known as an economy brand with
considerable problems with quality control. Few of their
designs were original, most knock-offs of lenses whose
patents had expired.
  Following the war Schneider became a very high quality
brand with application of air spaced elements in coated
lenses and very good QC. There is a vast difference between
post war lenses like the Xenotar and Componon and the
pre-war stuff.
  Whatever happened there was all to the good while Zeiss
was a shambles for some time.
