All this rhetoric is fine, except that thousands of heavily used guns without rotary or Greener bolts are still going strong and are still tight. Parkers, Model 21 Winchesters, and Purdeys are examples. Mr. Greener seems to imply that there is a second locking bolt on a Westley Richards in the 1862 patent. There is not a second bolt, only the bolt that extends into the extension rib. I'm sure he was aware of that.
