Concerning bolting systems, Parker Brothers didn't fall into the "multiple bolting lug" trap. They used one locking bolt and didn't try to improve on it by using more than one. It seems to have worked for more than 150 years without a change considering the Parker Reproduction and the Galazan AAHE still use the identical system. The doll's head rib extension was never part of the locking mechanism on a Parker, only a show piece that was not included on many Parkers from early models, to Trojans, to pigeon guns and single barrel trap guns up to the last years of production.
