There are a number of editions of the book. Early ones can bring higher prices from collectors, but the info in the book is not all that accurate. I believe McHenry was an attorney and an alcholic and Roper was fired by S&W for conduct unbecoming a S&W employee. At the time it was published it was a welcome volume, as nothing else was available on S&Ws. You did OK for the price you paid. Ed
