Campagnolo Chorus threaded headset 1990's
BSC/BSA (there is no marking but it was fitted to an English threaded fork, the headset will fit Italian threaded frames too)
5/32" caged top bearings, 3/16" loose ball bottom bearings.
There was some slight scratching on the bottom cup that I polished and buffed. I tried to get it in the picture as clearly as possible. It is the part with the text 'ITALY ——— BREV. INT'. The top nut has a few tool marks. The sides of the headset that are not photographed are flawless.
The bottom race has some slight pitting in one spot (last picture). The rest of the bearing races are smooth. I packed the headset with the ball bearings in some light oil and was not able to notice the pitting.
