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

[WA1KBQ at aol.com]

I have seen them both ways but then  Hallicrafters never really stuck to a 
plan. Perhaps cadmium plating along with  the chassis and tuning capacitor 
frames? I have an SX-25 here with the narrower  SX-24 lid installed in the top wh
ich means the hinge is about 2 inches back from  the rear. Also, there are many 
receivers out there that do not match published  schematics.

Regards, Greg

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.
