Ed I won't argue about case colors fading but I will say this---> I have a lot of L.S. Starret tools in my machine shop. Some of these were my Grandfather's. L.S. Starret case hardend/colored some of their tools like surface gages etc. After over 80 years of daily use by my Grandfather, my Dad, and now me, those colors are still there. They have had sweaty hands, cutting oil, swarf, and you name it on them. At the end of each day they were wiped with a clean rag and put back in the tool chest. Why a gun doesn't keep its colors and my Starret tools do is beyond me. My 1900 Remington has one small speck of its CCH left but you know what? It will stay that way. I kind of like it the way it is.
