DISRAELI GEARS
The Centaur was launched in 1989 as a lower cost alternative to the 1988 Campagnolo Euclid. As far as I can tell the only difference was that the inner parallelogram plate was a steel pressing - which was presumably marginally cheaper than the Euclid's aluminium forging.
I believe that this is a second generation Campagnolo Centaur from 1990 - with a cable adjuster.
