A friend and I both own Civil War ship model companies and we were discussing the subject when I asked what he thought was the best book on the subject. He recommended the "Civil War Guns and Ordinance". He personally doesn't own a copy, but he knew one of the authors was Wayne Stark, but that was about it. A friend of his some time back let him copy some of the many technical drawings from the book he owned. Owning a model company, having a copy of this book would come in very handy if I can only find one.
FWIW.
