Finally got an original Singer 112W140 sewing manual in good shape at a decent price. Most of the <$10 ones were ratty, and the better ones > $20. Happy I got this one for $16.. no holes/rips/tears.... the spine is taped, but I was just gonna cut it to scan it in anyway.
Most of the free internet manuals are B&W and almost all of the detail in the photos is just a big black blob.... not good when a diagram is trying to show you how to adjust something and all of the small parts are just a big blob.
