T,
That gun is the famous Lancaster "Wrist-Breaker" also known as the Model A. It was Lancasters top of the line until the advent of the Baker designed 12/20's. It is a back action sidelock, ejector, self opener. It is a Beesley designed action, brought out 4 years after he designed the famous action he sold to Purdey. These Model A Lancasters are my favorite.
