I have a book somewhere about GE and their work in developing (turbo)superchargers, but I cannot remember seeing anything about this airframe in there.
You might be thinking of
Seven Decades of Progress. It's GE Aerospace's company history. It was updated once, the first word in the title going from Seven to Eight. However, I don't think this was the book it came from, especially given that Larry said this was from a Kindle edition and
Eight Decades of Progress was published in 1990.

My best guess, given the detailed caption, is that the picture is from
The Douglas B-18 and B-23: America's Forsaken Warriors by Dan Hagedorn Sr. and Dan Hagedorn Jr.
