Yes, entirely possible.It's all a little too perfect to be done after market - and it's in the original box. I wonder if they were trying to emulate the Shimano Sante group with it's pearlescent finish? I've seen quite a few factory anodised vintage Super Record parts (gold and black) but never anything as wacky as this. I suppose collectors will always pay over the odds for rare pieces.
They did a huge range of mods to Campagnolo ... some were quite beautiful, some not so much :-DI like the Swiss custom made ICS parts. They were gold plating Campagnolo 20 years before anyone else.
It's definitely AthenaJust looking at it, and as a layman, it appears fairly low-rent. I'm thinking Xenon type level.
