This is one of those niche books that might be wildly popular in some areas and the book equivalent of a doorstop in other areas. Here in Michigan, this book could have an audience. In my library, it is not unusual to run across retired auto people that have niche interests in cars. Just the other day, I had a long conversation with one of these guys about the development of carburetors over time. He even came back the next day a showed me clippings he had been saving over the years. Before I knew it I was searching google patents for some carburetors from the 1930s.  (BTW, I love the more esoteric discussions with patrons.)
