The Reilly gun SN dating chart was made assuming that over the course of a year, gun orders would be pretty consistent. But thinking about French gun making, Manufrance always diverted to making bicycles in the late fall, winter, and back to shotguns in summer of each year, might it be that gun orders surged in late spring, summer of each years getting ready for the fall? (Reilly had an advantage here in that he delivered his guns within a month while others waited 6 months or more). Reilly perhaps tipped a hand in this question with this 1857 ad showing he was rebuilding 100 unordered guns preparing for summer orders.

There are Existing SN sales records for Pape, William Evans, Purdey and others for the 1800's time frame. Is there any historical evidence for gun orders per month? Can these be quantified? One would assume this would be pretty ubiquitous across the industry and might be used to hone dating chart numbers.
