You try brush electroplating it yourself: http://www.bikeforums.net/classic-vi...l#post18677059

... but you have to deal with the pitting first. I'm about to electroplate a 1950's Hetchins also with surface pitting. My strategy will be to electroplate copper, silver braze the pits, then another layer of copper, and finally a nickel-cobalt alloy. It takes time and effort to get a good result.
