I have that book, and have used it a lot!  It is mostly for anyone who
is concerned with designing _new_ instruments or parts, or for making
improvements to a pneumatic device that was poorly designed at the
start.  It's mostly an "idea book", giving _many_ ideas, including
several untried designs that look better on paper than the parts that
are out here already.

If you have _any_ inventive spirit, get this book!  If nothing else,
it will tax your brain and get your inventive juices flowing, which
I suspect is exactly what it was written for!
