msycamore said: Thanks for posting this! Well, it's a quite clear audible edit at that point. Hmm, this is weird, is there a possibility that you have repaired this segment at some stage and forgotten about it? It doesn't sound like it, maybe that print was damaged at that point?

No repair was done by me, and the scene doesn't correspond to a reel change.

I don't think it was a case of damage to the print. If there is another 70mm bootleg of ESB (mono even), perhaps it can be compared?
