John, I always thought the Bentley patent allowed you to cock the gun from the outside, but I have never owned one. Now, I am not sure if it is a barrel cocker, too, but would guess it is. That would make it like the Fukert patent which is a barrel cocker, but can also be cocked, albiet not so easily, with the thumb pushing the vestidual hammers. Maybe someone out there has a Bentley patent and can help.
