Good morning. So I have this early model Dura Ace rear hub. I an unsure what model it is. Dura Ace painted lettering has worn off. Dust caps say "Dura Ace" Uniglide freehub has evenly spaced splines, I am told only an early Dura Ace casssette fits. So my questions are:
A. What model hub is ths?
B. What cassette fits it?
Thank you.
