These C-pulls are probably the only Shimano component that was sold as three different models. Campy was famous for running the same component down through multiple model names, especially in the 1990s.
I have a NOS set of the "Dura Ace" and at one time I had the "Tourney" version which may still be buried out in the garage somewhere. I wondered at the time I bought them why NOS Dura Ace center pulls were so cheap, then I noticed they were eerily "similar" to the Tourney when I compared them side by side LOL.
