Coincidentally, I was preparing this one for sale today when I took a break to check my email, call a potential buyer back and check C&V!
The shift levers are the rare Huret variant of the Retrofriction design, wherein the friction resistance is only in exact proportion to the cable tension.
The cable end pulls directly on one end of the spring-wrap clutch spring, and the lever itself pushes on the same other end of the spring to unwrap it. This is the most sophisticated retrofriction lever design of them all, so I am hoping a buyer will ask me to put more-common shift levers up on the bars!
I believe it's an '82, all the componments are French.
