I'm not that well up on sound production using optical tracks - but surely
they were sound only rather than comopt?


Indeed they were sound only, but if you look closely at an optical track you
can see the modulation, a bit like seeing the waveform envelope displayed by
audio editing software (though smaller, and without zoom options!). That was
the "visual reference" to which I referred.
