I believe this group is within the timeline and therefore on-topic, although the formal introduction of C-Record came a couple of years later. I have a group that was issued to framebuilders around 1983 for exhibition at trade shows. Other than the calipers which are definitely a different design for delta brakes, I'm not sure how to tell the difference between some of the other items from first gen issue. Does anyone have an item by item description to properly identify the differences between prototype items and first gen? I'm particularly interested in the hubs as I'm not sure whether hubs came with this special issue from Campagnolo. These are not for sale, as they came on a rare, special bicycle thanks to Mr. and Mrs. GianTindaro Pergolizzi and Mr. J. Peter Weigle. Lou Deeter, Orlando FL
