I don't know of any collector who has replated the zinc. The chin scales for example would have to be taken apart and every scale done individually (?). The new plating would also be very shiny and artificial looking.....like the Indian repros being sold on Ebay. So I wouldn't do it but it is your piece. One other caution Jim..... gun oil and leather do not mix so be very careful about applying that to fittings or scales.
