Thanks Puggo. I think I'll do the preliminary CC based on color boosted GOUT and probably make some judgment calls of my own and then in the more detailed 2nd pass I'm see how it compares to the other sources and maybe make some adjustments based on that.

And I guess that the fact that the print isn't faded doesn't necessarily mean that it is a perfect representation of what the official 35mm and 70mm prints would have looked like, does it? Because I AFAIK it's a pirate copy, so it probably wasn't copied under lab conditions on perfectly calibrated equipment, right?
