On Puggo's version there are only three reels and reel 3 begins in the trash compactor and goes all the way until the end of the film. I assume that all 16mm prints must have had the same reel numbers and lengths, right? I haven't seen the Swedish version yet. Is it confirmed that this a reel change, or is it just damage? If it is not a new reel, then the ones on Starkiller wouldn't be 16mm changeover marks. In fact, they almost look like holes punched through the film the way they are white like that. Are they in the exact same spot for multiple frames? Changover marks are printed in and will remain fixed, if that just appears for a single frame each it's more likely print damage (the shape of the "hole" is even different in those two screenshots, and it looks very organically shaped, rather than the more deliberate cue marks you usually see).
