Hi Robert,
Good questions. I have seen SR w/alum. hanger & pivot bolts in r. der. with PAT. years 77,78,79. I wouldn't have included '79 a month ago. But saw my first '79 w/alum. just that recently. 1978 seemed to be the year that all SR r. der. came with alum. I have also seen examples of '77 & '79 w/Ti. 1981 was the first year of the new steel spindles (pins). Yes, brass ferrules were still used, even though that catalog #18 does not show the ferrule. Actually, in cat. #18, you can see the ferrule still in the front arm. They forgot to pull it out and assign it part # 82/A, as done in all the previous catalogs. Another oversight amongst many, in the scrutiny of Campy catalogs.
