LDDB indicates that Criterion’s Blade Runner CAV CC1120L was pressed by 3M and Pioneer USA. It also indicates that later pressings had a barcode. I have two copies with a barcode and both are 3M. Was Pioneer USA the initial pressing? With 2001 it was the later, so I assumed the same with Blade Runner. Having a hard time finding the Pioneer version. If anyone has any more info, or a copy for sale, please let me know. Thank you!

I do have a Pioneer pressing of that, it has the barcode in the lower left corner on the back.
Maybe it cannot be identified using the sleeves, but only by looking at the mint marks of the discs?
