Vintage campagnolo shifters
 

Hello I was curious about the differences in vintage campagnolo shifters. Specifically nuovo record shifters. let me think how to explain this....I've noticed that the guide on the shifters is a piece of metal that is either silver like the rest of the shifters or black. I've done a little research and it seems the shifters from the campy record group are all silver and the shifters from the gran sport and valentino group are exactly the same except the metal guide is black. I realize this is a terrible explanation and I hope you know what I'm talking about. I have the black but want everything to be from the nuovo record group so I'm thinking I need all silver? Thx

I could be off a year or two, but if I remember correctly, they eliminated the guide when changing from Record to Nuovo Record.

Nuevo record RD require less cable pull than The Modern Slant Panto, so your Down tube lever barrel diameter can Be smaller

I use <C> friction bar end shifters on my Old Rally , but SunTour ratchet Bar end with the Newer Euclid..

GS Downtube levers used to have a Housing Stop to run housed cable the rest of the way Back..

But FB knows more Campag Minutiae than I..

The black backing plate with cable stop guide was original, continuong a ways into the Nuovo Record era, which I will call began in 1968. The top tier changed to chrome plated about 1971ish
Not a model year designation, call it a running change and stocks just got used up.
The subordinate group levers often with the later units had slotted screws... But so did the early units before the ringed screws allowing finger adjustment. When the superleggero black pedals arrived some clients wanted the black plates for aesthetic reasons! 1978 ish brought the dropping of the cable guide. Soon followed by the design simplification of the lever. (Left out the closed C open C transition)
