I have noted that certain low end guns seem to retain their colors better than highly finished (well polished) surface of higher grade guns. Case in point I have a Hunter Arms Fulton that retains almost all of its color after 70 years while most of my A H Fox guns with about the same or less level of use are starting to fade or wear off. It seems to me that perhaps the surface preparation of the item being color case hardened would have a bearing on the durability of the case colors with courser surfaces retaining colors better. This is a very limited observation but I have seen many Savage 311's and Fox Model Bs that exhibit the same resistance to color wear. Both the Savage 311s and the Fox Model Bs have the same cyanide colors as the A H Fox guns. Any one have any thoughts on this?
