The hour and minute hands would likely have been silver originally, to match the "mirror" indexes. They would definitely not have been gold.
If the sub-second hand is truly gold colored, as opposed to the original plating having worn off, then it would not be original. An original may have been black, blue, or silver, but not gold with that dial.
Correction – you say that the indexes are gold colored (they look silver on your photos)? Then the hour and minute hands should also be that color, and would have been from the factory.
