Query: The Defintive Guide Found

After searching the internet extensively for information on the rigging of Continental cannons and carronades I got pretty much nothing. Within 1 minute of opening this book, I had everything I needed. Reviewing additional sections showed me the wealth of information I had just tapped. The internet may have the information I need, but not at one place like this book. Excellent print, excellent information and the drawings are absolutely the most concise and accurate I have seen anywhere. I hit the goldmine with this reference piece.
