911 finish triva-help!
 

I’m restoring a 73.5 911 Targa and over the years some of its original finishes have been supplanted by quite a mix of new finishes allowing determination of the original finish almost impossible.
I have three items I need input on and I’m hoping a few owners who have original 73.5 cars and/or parts might be able to help identify the correct original finishes for me.
I think most of these were originally Zinc plated but not 100% sure.
Thanks for any help!

Are you going to enter a Concours?

Doubt it but might. Since I need to do a finish, might as well do the right one. Devil is in the details.

Thanks
