I agree that the mainspring should not be plated which could indicate a re-plate at some time in its history. However, I'll disagree on part of the above statement based upon my experience and two full-plate Nickel examples in my possession. Both examples are full-plate nickel and have the hammers, triggers, barrel catches and extractor rods full nickel plated. I can't comment on full-plate Silver as presented as a possibly above but I'd guess the revolver is nickel.
