Just saw this... WOW! Can't believe there's another pre-DVNR SW disc! It looks like a different transfer than the one used for early SW VHSes, laserdiscs, and betamaxes.
Since it is 2:20 and not 2:35 but has more vertical resolution, is it possible this was taken from a 70mm print?
Though your early samples looked quite desaturated, the newer capture looks spot on. Keep it up.
