You can check the brownell's catalog on line, but IMHO, NO. Nickel is actually nickel plating over COPPER plating. Parkerizing is a phosphate finish. While there are cold blues that at best provide a pale imitation of a good hot blue, (i use them to touch up scratches in bluing) do not know of a "cold nickel" or cold parkizing" product that is even close to original.
Sorry-
