Also, I count 8 scans needed along with the field data. Another reason a document scan, DB and image server makes more sense - assuming they are paperless in some form. They could be old style and pull the book, make a copy...

I don’t know what Adobe Illustrator does there, but this is not a multi-layered PDF. In the ordinary Adobe Reader that everybody has installed, you can open a PDF, choose View > Navigation Panels > Layers, and you will see the multiple layers, if any. There are none in this PDF. Adobe Illustrator probably generates them, I guess.
