Hi all, lucky I read this one early, I myself have seen, & even have the parts here, seen the SL cast on several Campagnolo castings, they being late/last model undated NR and Rally/GS rear deraileur top housings. I am sure I've even seen it on arms as well, but they are in the garage, and I'm in the bedroom with the computer. All these are raised & not in relief. I always just condsidered it a change in supplier or inhouse mould designs.

I have not seen it on bottom housings, neither have I seen it on brake caliper arms, I myself tend to use Modolo brakes......regards wayne......
