The flatback action has a steel extension that sticks out from the fences. The top horn of the stock mates to this "flat back" part of the action. A stocked to the fences action does not have this extension, rather, the stock top horn goes all the way to the fences. Compare the point where the stock and action meet on top of the action between the photo of the gun in question and the Purdey in the following photo.
