Query: This gun book was a gift for my son.

I ordered this book as a gift for my son's birthday. He got it and said it is just wonderful and he was quite pleased to get it. As I found out it was the last one Amazon had and now is very hard to get so I am pleased to have gotten it when I did. It was sent quickly and everything went smoothly. Thanks, Amazon!!!
