I think there are a lot of misconseptions about the early vs late super record brake levers. Campagnolo produced levers in one way only - by stamping out a sheet and then cutting/bending it to the shape of the lever. Any levers that are drilled are merely record levers that have been drilled out. This is why very often they have a different amount of holes. Campagnolo first generation super record levers were produced between 1973 and 1977 and had the longer shallower curve and they were all bent after having the holes put in. If you find some with round holes then they started life as record levers and were drilled out. The type Mr Denny refers to as "first generation" are nothing of the sort. They are post CPSC levers so are the second type of lever. Nothing really changed from then on save from the "brev camp" being removed from the cable stop ends. Mr Denny certainly does know a lot but I do not think that his expertise is campagnolo going by past dealings with him.
