The truth may be somewhere in between. When the crank was made Campagnolo was stamping the chainring bolts. For those who really really want to know it can either be Brev. Camp or Pat. Camp. and I never cared to remember when the change took place. But, later Campagnolo stopped stamping them, maybe after the patent expired. So, they may well be Campagnolo chainring bolts and nuts but just not from that era.
