Just finishing up a Fusil de Casse for a customer and was discussing the finish. These were almost always polished "armory" bright from the factory with some fire blued as a special order, but the discussion was what happened next. Prior to 1800 most arms were done this way. Most soldiers were issues brick dust or something similar to keep them polished and rust free but what did your civilian long hunter or pioneer do? Personally I can't imagine wanting my hunting gun to shine like a diamond when the sun hit it but did they immediately put something on it to cause it to patina or did they try to keep it bright? Given that a new rifle or smoothie was a considerable expense you know that they would have taken care to keep it sound and just letting her rust up just doesn't sound like something they would do. I've read lots of old journals and diaries but don't remember ever seeing a reference to this.
