Reading through the production steps in the articles really gives you an appreciation for the complexity of manufacturing modern firearms.
There was also a good description of rust bluing (referred to as "browning") in the barrel article, as well as the chemical mix for the rusting solution.
I'm still a bit amazed that Springfield Armory would go to this level of detail in published material during war time (even though the US had not entered the war at this point). I wonder if there was a shortage of production machinists that they were trying to attract with the articles.
Seeing this information just makes me appreciate our precision firearms even more...
