I still can't find it! When I type in what you said, I only get the book by the other author (Basebase Law) - not the one by Bays. And when I look for Bays as the author, I only get the other book - very frustrating!
I looked at the one the Smithsonian has, and it's great - but I'm more interested in 1890-1940 era machines.
This is the only green one I've found, and it's the other title - but it is by Carter Bays.
