I just received my copy a week or so ago and have been poking around in different chapters until I get enough time to seriously read it. I like the stories about David Trevallion's apprenticeship in England and believe that the text and photos do a good job to explain and illustrate double guns. I have been using an old side by side to play with taking apart and putting back together and general messing around with. This book is a help for figuring things out. The book has also helped me to look more critically at used guns I am considering buying. I like it.
