That’s essentially the same type of print used for Grindhouse, so save your money. The LPP currently scanned has a lot of potential for restoration, and has even been scanned in 4k for most if not all of it.
You misunderstand. I wouldn’t buy the print solely for this sites preservation projects. It would just be a neat thing to own.
I am aware this is the same type of print used in this grindhouse, I wouldn’t try combining it with an IB Tech and calling it original. I can only assume their copies aren’t perfect (nor the one on eBay). Combining the eBay one with the others already available could improve the overall quality.
What I am wondering is if it would be at all helpful to the current projects and whether or not I would receive help if I tried to restore/preserve it or even combine it with current releases (i.e. cleaning, swap scans, etc.)
