I do agree that it is plating, but from what I can see I think it is clear plating, with a slight yellow tint that has the rainbow effect and then olive green paint and overspray on top.  Here are a couple of close up pictures, notice the rainbow areas don't look olive green.  The picture the inside of the back shows the clear plating on the flat areas near the gasket and a light yellowish tint on the curved surfaces and internal parts with some rainbow effect. I believe that all of the horn parts were plated in that manner with some surfaces being painted olive green as a top coat. Just my opinion.

 

 

It surprised me that the inside was so well preserved after 50 years and 150,000 miles in a wet climate. Those paper gaskets sure worked well.

Thanks for the help.  I believe you are probably right.
