[Fred Nerks]

Is this the book the images came from?

Do you recognize this image in that book? Is that image in black and white or is it tinted?

Is this a black and white image from the same book?

It's beginning to look as if the yellow tint is nothing to do with your scanner. The tint may be in the images themselves and that is how you have reproduced them.

Those pictures are all on white background paper. I can do B & W copies from the book I have and then scan those in.
