Suntour Grand-Prix derailleur.

[ferrus]

I doubt anyone’s going to be interested in buying this at the price, but posting it here because you seldomly see them. I’m not sure they were ever available in Europe.
A landmark mech that pioneered the slanted parallelogram principle. Interestingly, it’s also a ‘Rapid-Rise’ (low normal/default) design.
It probably worked better than Campag’s finest nearly 25 years later!

Some info from Disraeli Gears. Note the mech featured there is labelled Gran-Prix. The eBay one is a Grand-Prix!

You can guarantee it'll work better than Campag. Huret eco works just as well in my experience

Huret looks crap on the mantelpiece though

I used to hate those feckers with a passion. The plastic plug was the rotten cherry on the cake/cack.
