If the underlying material is copper, why not one of the ion-exchange instant silverplate solutions like Cool-Amp or Caswell Silverplater?  They deposit a very (one molecule) thin layer of silver that might do the trick for a restoration.  Caswell also markets brush-plating electrolytic silver (and nickel, gold and a whole bunch of other metals) kits if you'd like something more substantial..  (http://www.caswellplating.com).
