Early Campagnolo brakes. These are for older bikes that don’t have a recessed mounting nut. I have had many pairs of these go through my hands. This is the first pair I’ve had that the brake pad still has the mould parting lines from when they were made. These are in my opinion new. They shore wear from storage. The chrome plated steel parts are the only tell. Brakes are a 9.5 and with a little of your time you could bring them to a 9.8.
