<VV> LM Engine Bay detailing

[chris mann]

Hi guys:
I am preparing to send out a pile of parts from my winter 1969 engine detailing project for cadmium plating.
My question is what items were plated originally when the car was built?
I have all the screws, nuts, bolts, washers, the carb balance tube, the connecting throttle bar, and the oil cap so far.
Was considering the engine lid prop rod and the magnesium fan too, but am not sure if that was plated or not. Can any of you provide some insight please. I want to do once and do it right.
I have three options for cadmium plating, silver cadmium plating and gold cadmium plating. I would imagine I seek either cadmium or silver, I don't know which one is correct.
Thanks!
