Wayne,

The original plating Porsche used was just cadmium. It had a dull silver color and took on an almost “fuzzy” appearance when it had been out in the weather for some time.

In about ’68 Porsche added the “chromate conversion” process to the cadmium plating and produced the gold color for the first time.

In the late ‘80s the cadmium was eliminated and the zinc with gold dye replaced it. With two gold color parts next to each other the color difference is very apparent.

I can send you some virgin cadmium-chromate conversion parts if you want.

Best,
Grady.
