Sorry about the error in my last post. Not only do late Trojan Parkers have no doll's head, no Trojans have a doll's head. While I'm here, I will take Miller's lead and mention that DS and I Grade Lefevers have no doll's head. All of these guns are among the most durable of American shotguns. Did I leave out L.C. Smiths, Foxes, Model 21s, Ithacas? 680 series Beretta over unders have a device that serves the purpose of putting pressure on the same area of the breech where a perfectly fitted doll's head is supposed to put pressure. On higher end 680 series Berettas, this device is made replaceable, supposedly because it has a purpose. However, it is obviously not neccesary for this device to be in good contact for the gun to be durable, because in many models of the 680 series, it is not replaceable, and these guns also seem to last several lifetimes of shooting.
