Playing catch- up here:

I am pretty sure those film frames are from IB Technicolor. The ANH crawl frames show considerably more fading, which matches with the Senator print. (The UK prints had the 1981 crawl cut in on pre-LPP Eastman.)

The other reason I think it could be IB is because there are no Eastman edge codes on the actual stock. There is only occasionally a printed-in negative Eastman edge code. And I could have sworn some of the images had a gray soundtrack.

I have hundreds of images from this movie_maniac guy, I’ve been saving these pictures for months. I can send more if needed. These are obviously captured off some kind of light table or something. The hue of the clear film stock looks different depending on the photo, so I’m thinking there’s auto white balance at play here too. (I have Sandpeople/Kenobi canyon stuff, the unexposed portions of the film and the light shining through the sprocket holes look bluish instead of white on those.)

I’m not sure if this person has dupes of the same footage, has cut up bits of multiple prints, or if they are different 5-frame strips from the same print. But either way, I can throw all the images up in a ZIP and post them up somewhere for Dre. Though they may raise even further questions.
