1929 Sport Coupe : Chrome or Nickel ?

[26Tguy]

Hi Fellas.

I am hoping someone can give me a definitive answer as to what parts should be chrome, nickel or cadmium plated on a 1929 Sport Coupe that was assembled in August of 1929.

I have read MANY contradicting opinions and I know it depends on the assembly date as chrome seemed to used more widely in late 1929. I.e. the radiator shell, headlights, etc.

Thank you, in advance for you time and information sharing.
