I think a much more complete history (biography) book of Arthur Savage waiting to be written...
I don't know about an entire book, but we can definitely fill in some of the timeline cracks in more detail.
There are a few more areas that are a little fuzzy yet. Once one starts to look who knows what may pop up.
I re-read the AWS bio in Bailey's book that was done by Arthur's great nephew which is probably the best known bio to date.
And even in that bio it says something to the effect that "Arthur either invented some kind of tire or has something to do with tires."
I guess we now know yes, Arthur "had something to do with tires"...
