Need some help identifying a Campy bottom bracket I have. It came from a 73 bike so I figure it's that era. The rest of the bike is Nuovo Record so I figure that it's NR. I know its english. The part I'm having a hard time with is the marking on the spindle says "68-SSX3". When I google this it tells me it's for a triple. The spindle is 123MM. The crank that was running on this is a Campy Nuovo Record Strata and it is a double. Both cups is marked "Campagnolo 36 x 24 Brev. INTER. So is this for a triple as in triple crank? Didn't know they existed back then. Anyone out there know what I have?
