Peter, I may have my history a bit confused then.  I understood that the
system represented by the swastika, and subsequently by the square, was the
system Blumlein had developed for Columbia.  This was the system denoted by
a "C" on Columbia discs, and the Gramophone Company was able to use this
technology when they joined with Columbia to form EMI.  If I have this
wrong, please set the record straight!

Thanks,
