[Hallicrafters] SX-25 vent "fin" color?

[Carl]

The fins on my SX-24, SX-25 and four PM-23's are not painted but neither are 
they bare "natural" steel which would not be without severe rust after all 
these years.

They do appear, under magnification, to have a very thin plating which may 
be nickel. Several fins and bars here are showing signs of slight rust where 
the plating has worn thin or has a thin scratch.

Take a fin to a plating shop and they can tell for sure.
