Also: I downloaded the 4 volumes off the internet archive.
I take pdf of old (Bible Related) books, break them apart into individual pages,
then clean up the backgrounds and enhance the text (in photoshop)
It’s a bit of work, would you be interested in seeing my finished results?

When there’s a word obliterated by dirt, I have another volume – that was a very “dirty” scan
and did some cut & paste to replace that word.
I also created a log book for each volume – containing every page where I “cut & paste” a word or 2.

The best I could find that might be of some help (short of an English version of this PDF) is here: http://www.ericlevy.com/Revel/BenChayim-Intro.pdf

Please remember that we have joined all 4 volumes together so page numbers might need to be adjusted.

Also, a quick scan through it and the start and end pages might be more what you are looking for….
