I believe there is one manufacturer with a "stainless steel" finish where they named the color "stainless steel" and it is a coating, not actually stainless. Possibly H&R one of their combos. I can't find it now, although on this page they list "stainless" in the sidebar describing the page and nothing on the page appears stainless.
Maybe one of the cheap 22lr revolver makers.
Wherever it is I saw something thought it was a great deal, almost jumped on it without thinking, then looked it up and was quite disappointed.
