Re: How restore the "gold" finish of TR6 door latch?
I think that is a cadmium plating, you can take it to a plating place that offers the service, or Caswell sells do it your self plating kits, or Eastwood has paint to try to mimic it. No experience myself, but my first attempt would be to try and find a commercial plating place, from what I've read if you can find one its not a very expensive thing to farm out.
