As requested here are some pics of my Verney-Carron 450-400. This gun has a second barrel set (pictured) in 12ga fully rifled for shooting slugs. If you click on the picture you can make them larger. Unlike production guns all of the Verney-Carron custom shop guns are made to order so that there are seldom two of them exactly the same. A PDF catalog can be seen here www.verney-carron.us
