Yours would have been blued.  Parkerizing (zinc phosphate) was used when rebuilding previously blued pistols.  If yours was rebuilt it wouldn't have no finish remaining.

BTW, have you ever seen a magnesium phosphated gun?  This is a black "Parkerizing" that might be more appealing to you than the standard gray or gray-green finish.  Not trying to talk you into anything, really, but I am suprised Parkerizing doesn't appeal to you.  To me it just screams "military."
