John, I notice Drew's picture of a boxlock is in the 42,000 serial range. That range from maybe some 38,000 guns through 49,000 contained many guns that were made up from "parts on hand" Could be a mixture of models on one gun. One cannot bank on those guns being representative of particular models. Drew's gun seems to have the 1909 Paragon cocking hook, and maybe the ejector is the same or similar.
