Restoration Qs...Nickel plating

[d.j. moordigian]

On current Nickel plating, which looks way to bright compared to
the original plating. I think it was "MikeK" who said / mentioned
the different "brightness" in the plating. The questions..

What did Ford use on the Model A?
Is there a "word", part "number" or a way to "describe" the
plating used from 1928-1931......too get the correct finish?
