Yeah the franken-print idea is something which might plague this. The key is though we have two official and two bootleg sources all pre-ANH but each set has one of each credit version.

Leaning more towards this being an opening day, print variation thing, not something they changed as they made new prints. Here's why:

Three Audio Versions & Two Credit Versions

35mm two-track (four-channel) Dolby Stereo = English 16mm & widescreen pre-ANH bootleg (does not have 'close the blastdoor') + 'Draft' Credits

70mm Six-Track Dolby Stereo = (does not have 'close the blastdoor')

35mm Academy mono = Swedish 16mm & cropped pre-ANH bootleg (has 'close the blastdoor') + 'Refined' Credits

[Note: to add in some extra credit confusing the Swedish visual field is larger then the English, so don't get the 16mm cropped confused with the pre-ANH bootleg cropping. Same term, two different used.]

In the Puggo restoration video of the Grande (english 16mm), he mentioned how he used the Swedish audio for this project but the English 16mm video, which might make this a franken-release of sorts. He noted that he was required to make audio revisions as the two prints didn't match up. Not sure if this is caused by actual changes or just something in the preservation of this particular print. The video mentions certain points where the spockets required fixing for instance.
