Not sure about the 8mm, but it was mentioned a few posts up that the ending footage of the medical frigate was different in some releases. I know that the model footage was re-shot by George and ILM at the last minute. It seems some test audiences would have seen this alternate footage, but all the release prints had the new footage. I believe the Definitive Collection photo galleries has this info. I tried to look it up yesterday, but my Dr. Gonzo discs wouldn't play.

And I can send you the Classic Edition ESB, but it could be a week or so.
