pms seem to claim that a guy named king was tasked with the job of coming up with the bolting system for the new parker hammerless gun in the late 1880"s...
story goes, he looked around and decided to use the westley richards systems, as patented by messers anson and deely, in the 1870's...
in order to avoid patent infringement problems, king modified the wr bolting and forend latch systems, enough to make the parker systems patentable...
one of those modifications was to eliminate the wr top bolt, but to retain the dolls head rib extension...
like eightbore said the parker single bottom locking bolt system worked like a charm...as does the parker forend latch system...
and if either does become loose, they are quite easy to tight up...
