Vintage NOS Campagnolo Super Record Crankset! A Super nice Crankset! Driveside is all NOS but has some nicks, see pic #8. The non drive side crankarm is not NOS & has some nicks to the left & right of the shield on the angle surface. See last 2 pic’s. These were manufactured in the 1970’s & 1980’s! Both arms are 170mm. Perfect for building a Steel frame Vintage Bike! This is a Very Nice Crankset, but just doesn’t qualify for a showbike. But with an NOS non-driveside arm it could qualify for show quality.
