This is also my understanding. When I first restored my 1966 PX10 I took it into an LBS that had an old Hungarian mechanic who was formerly a race mechanic in Europe. He was going over the bike and naming the components. When he came to the brakes he just said "Mafac Racers", even though they are the ones we're referring to as Dural Forge.
As a reference point, my Racers have bronze bushings and red plastic washers. They have no oil holes. These were original equipment on my Peugeot.
