Even weirder...so does that mean the revised-opticals version was re-cemented at the IP stage from A/B-roll? (And would this mean the "new" IP from 1985 or whenever would have different splice marks than "revised" prints from 1977-78? Would the IB prints have still different splices due to not coming from the same IP?)
Maybe we should look at the cropped nth-generation bootleg of the revised version mono print (if we can make anything out from it)...
Another question - do the printed-in white splice marks that show up on the original P&S home video transfer show up on transfers not from the same source, like the Technidisc? (Or is it too tightly cropped at the top?) And then there are a few printed-in BLACK splice marks - on AMPS, -1 posted a shot-by-shot breakdown spreadsheet that none did of the Spanish LPP, and he put down a note that seems to indicate that the repeated frame of Vader from the lightsaber duel has the same black line running across the top of both frames as you saw on the JSC...
