As it was explained in another thread, my recently acquired 1924 vintage A.H. Fox AE 20 Ga had lost all its case hardened colors. Michael McIntosh mentions in his book on AH Fox that Chromox steel, presumably of Belgian origin, started being offered in the early 1910s, for both barrels and frames (pp. 139-40). He explains that: "When the case colors disappear.....the older steel turns a soft dull gray; Chromox, on the other hand, goes as bright and silvery and shiny as a new nickel". My Foxs frame shines as polished silver coins.
My question is that short of a case hardening process, there is any simple (chemical) proven process by which a Fox Chromox frame may obtain a dull gray or French gray?
