Kensal, I understand what you are saying. If I recall correctly, the salts bath is run at a higher temp in order to blue nickel steel parts without getting reds or purples. Don't quote me on that though. But it sounds as though some guns that were originally blue can turn purple over time. As with my Mauser M66S, I assume the Winchester guns that turn purple were not purple when they left the factory. If that's true, isn't it possible that a Simmons re-blue could also change color over time? I have never read an explanation for why this color change occurs or if it can be prevented.
