Default Re: 32 Parts - How to tell Original from Reproduction??

Zinc plating tends to have a hint of blue in it while white cadmium tends to be on the white side, sometimes with a hint of yellow in places. Normally zinc plating will have a bit of a gloss (depending on the condition of the underlying steel and the age of the plating) and cadmium will have no gloss, especially if it is old, again depending on the condition of the underlying steel. The color is the best guide to the difference without regard to the age of the plating.
