That may be the case, I certainly wouldn't discount that if that is true...I have just never seen a factory Nickel plated Steel shell. Ever Nickel shell I have come accross is stamped brass. All the painted ones, steel. It just seems like too much work to brass plate, (possibly copper plate) then Nickel plate a steel shell.....then just stamping it from brass and cut out at least one step from the process and save money....something Ford was all about. It seems logical to me. If I am incorrect, I am okay with that and thank you for the correction Posted using the Full Custom H.A.M.B. App!
