Not the one yo umention, but Wade’s monograph on hand scraping is available at the Internet Archive:
https://archive.org/details/Scraping1
Search there for other old textbooks that touch on the subject.
Some modern takes on the subject can be found at Japanese machine tool manufacturers (Okuma, Matsuura).
There is a ‘machine rebuilding’ sub-forum at Practical Machinist, where King Richard presides. Peruse that archive for other texts available.
Connelly’s book is avaialbe online as a pdf copy.
Not so much on scraping, but on the results you are trying to achieve from scraping (alignment/accuracy), the Moore Tools books are worth obtaining. Again, ‘Foundations of mechanical accuracy’ is available online as a pdf.
Another good one on the same theme is Schlesinger’s ‘Testing machine tools’, again available online as pdf.
