I bought this framset back around 1976 thinking it was a Nishiki Profesional.
The serial # is E22950 and does not come up with the above charts. I repainted it years ago and put the Colnago decals on. I also had Campy low flange hubs built up with road rims for fixed gear training. I just ran across a craigslist ad with a 1974 Nishiki Pro with my same style fork crown. I didn't see any other bikes with serial #'s that started with E. Does my framset look like a Nishiki Pro?
