Since we're asking for shifter clamps today, I am looking for one that says "Dura Ace" between the bosses. I don't know, however, that they made one. The one I have says "Shimano" and may be correct for early Dura Ace (?). The catalog scans and photos often do not show enough detail to see what is written on the band.
Thanks,
