From the Campagnolo family album. Three generations of levers: 2009, 1998, 1992(?).
From left to right: 1. 2009 Centaur Ergopower, 2. the first year of the last generation Record Ergopower, 3. this looks to be a brake lever from the end of the C-Record era and the first year of Ergopower (which still had the pointy hood a la C-Record). It came with a set of Euclid canti’s intended for use on tandems.
