The clip definitely looks like it's from a VHS but the colours definitely are not the 2004 SE. So that leaves us exactly nowhere in finding out which version was archieved; people here seem to assume that it is the original but I wouldn't be so sure about that. They asked Fox for a print, Fox gave it to them, they archieved it. Now, you may have noticed that ever since the 2000 VHS and LD release the butchered versions were never marketed as Special Editions, so there's no reason to assume the situation is different with film prints.

For our cause it would actually be better if it was the SE, because that way we could point out how Lucas is trying to change history. If it is the original, it weakens the whole film-preservation part of our arguments.
