It seems the only reason where something is mfg'd would be important will be if we can find the press that had the scratch or are able to put a sheet together by locating it? But generally I would agree that where a card is produced doesn't really help with where they were located on a sheet. Those scratches might help though....

Neither should the %. If enough scratches are found to connect them and
come up with a sheet or partial sheet layout it doesn't matter how many
cards you have to look through to find them. I have saved scans from quite
a few that are listed on ebay and there are a lot more than the seven you found.

I didn't want to go back and look through all of them but I did look through
a few pages and found twelve but I could only attach nine links.

I also don't follow what you mean by varying ink streaks, they were caused
by something scratching the surface it's not like someone drew a straight line
through the back plate.
