Original Campagnolo C-Record rear derailleur, first generation, made in Italy, approx. mid-1980s.
Early C-Record version with the characteristic engraved Campagnolo shield logo on the parallelogram. Classic polished aluminum finish with original Campagnolo pulley wheels.
Inside, there is an embossed number "1", presumably a manufacturing/production mark. It is not the PAT year code found on older Nuovo Record rear derailleurs.
