Thank you Nick!
That helps a lot. I will have to look at the HW5 files instead.
If I understand correctly, they are not yet digitized. Do you by any chance already have scans of some files that you would be willing to share?

I also saw that it is possible to request scanned copies from the National Archive. Do you have any experience with this process? If yes, do you think they would be willing to scan large amounts of files, and how much would you think this would cost per page?

I am also unsure how many pages we are speaking about. You mentioned that it goes in the tens of thousands in total. So it is a few hundred pages per file?
