Those are NOS door handles, but they do not have the C3XB-6422404-B (LH ..405-B) part number cast inside the handle, it's another number, still a legit Ford part but not with the original number.
I had mine re-chromed (they are still at the platers) but I can't find my quote sheet, I think $60 each. My handles had micro-cracks but no pitting. If they are pitted the costs go up. I got the buttons rechromed for $10 each, the inside brackets, levers, screws and pins gold zinc plated for about $10 total (different plater, different process). The studs, screws and nuts were clear zinc plated months ago. The springs were bead blasted and phosphated, the O-rings came from a local hardware store.
