Being a bit nit picky here. The term used in the FAQ to describe the forward (muzzle) end of the floor plate could lead to a bit of confusion. Doll's head is normally associated with a rib extension that fits into the receiver.
Doll's Head - A rib extension on a break-open gun, ending in a circular or semi-circular shape in plan (resembling the head of a doll), mating into a similarly-shaped recess in the top of the receiver, designed to resist the tendency of the barrels to pull away from the standing breech when firing. Because an action's centerpoint of flexing when firing is at the base of the standing breech, not at the hingepin, a passive doll's head extension makes an effective extra fastener, even without additional mechanical locks operated by the opening lever.
