I have two of the Campagnolo crank dust cover tools with the little pins. I didn't notice today that one of them is chromed and has the 50th anniversary markings on it. I'm not sure what parts and tools came with or were available for the 50th group, but this is the first time I've ever seen one of these. If anyone has a list of what else was offered with/for the group, I'd be interested in seeing the list. Only other oddball part I've seen is the Cinelli stem with the 50th engraving.
