While the topic is floating 'round..................
I've been cleaning and detailing a set of "Gianni Motta" pantographed Campy brakes and noticed something. The backside of these arms are as well polished as the fronts, as nicely finished as any area of any Campy part I've ever seen, and stamped "SL". Upon inspecting several other Campy brakesets I found the odd flaw, cast mark and generally a finish one might expect on the backside of something where the backside isn't likely to suffer close inspection.
Did Campy make a "SL" brakeset I've never heard of?
Was this mark and the extra attention added by the pantographers?
Anybody have any thoughts on this?
