Shoot for the late 1870s and 1880s and go from there. Its already been established by researching predecessors that Reilly did in fact make guns in the early to mid 19th century. We are mostly interested in breech loading guns. And like I said....just because theres serial numbers and pictures of guns, swords, pistols, etc does NOT mean that maker actually made the things. Just because s company was listed as a gunmaker DOESNT mean they actually manufactured the guns. Selling guns that show up to your factory completed, or even stocking , finishing or subcontracting those jobs on a barreled action doesnt qualify a company as a gun manufacturer in this day and age and just barely did back in those days. A lot of the companies that built ground up percussion and flint guns continued to use the gunmaker-gun manufacture label long after they ceased to actually build entire guns.
