Hi, I have some Campagnolo rear derr pulleys that do not have the Campagnolo lettering. They are Campy for sure (i'd stake my life on it) right down to the brown grease with the unmistakable smell in the blue package. I have been using them as N. Record replacements on repairs for 20 years and someone pointed out that they had no lettering. I have a bag of them and never noticed. Does anyone know if the early or late pulleys had the Campagnolo lettering? We bought them in the late 70's or early 80's from a distributor that was going out of business.
