"I don't know enough to frame an informed question so, this will may be clumsy. For the upper end models which I think were Master Pro, Professional, Equipe - were they available in a silver (polished aluminum or anodised) or a gold finish?"
I had a full set of silver anodized Mavics back in the day. I also have pictures of Sean Kelly with silver levers and calipers. Never saw any gold ones that I recall.
