Hello hufflepuffle,
The scans for pages 1 and 64 look very crisp, but the scans for pages 2 and 63 look a bit out of focus, and as though they were not scanned flat. Did you take those pictures with a camera? I assume you were trying not to damage the book by scanning the inside pages, but the quality will be much better if you can get a flat scan of it. If you can't, I understand.
It also looks like there are a few rectangular regions that were copied / pasted on pages 2 and 63, to replace missing page corners or page numbers. I am thinking that one of the scanners or editors here could attempt a better repair job, if you have the original images.
Thanks for providing these!
