An awful lot of this is already in my Campagnolo Timeline; for example the entry for 1978:
1978 - C.P.S.C. (Consumer Product Safety Commission) mandates changes to NR/SR. Included are a front derailleur lip, 1.5 mm increase in spacing between crank spider and arm to clear the front derailleur lip with corresponding increase in bottom bracket axle length, a curved quick release lever and ball-end added to quick release conical adjuster, dome-shape added to quick release cam lever on brake calipers, plastic covering added to the wheel guides on the brake shoes, and plastic safety-shields added to rear derailleur screws. Logo on brake hoods changed from "world" style to "shield" style. The word "Patent" is changed to "Brev." on the chainring, chainring bolts and crank dust cap. Tullio Campagnolo is bestowed with the Stella D'Oro (Golden Star) award by the C.O.N.I. (Italian National Olympic organization) for his contributions to sport.
I would be more than ecstatic if someone would volunteer some new info!!!
