Title: Not Great
Review: This appears to be a reproduction of an old book of unstated vintage. My guess would be from the 1870 to 1890 period. The illustrations are a bit small and a bit crude... I felt a few of them were misdrawn enough to be unworkable as shown. A lot of the mechanisms shown are really basic things like simple levers or pulleys unworthy of space in a serious book. And the whole book is poorly organized. My advice is to save your money for the "Ingenious Mechanisms" series.
