I I'm just interested if anyone else has some weird Campagnolo factory finishes, I always thought that were very staid and boring when it came to small run custom production. Maybe I was wrong....
Spotted these online also - appears to be factory anodised graphite Record brakes. I've seen similar finish Super Record chainrings and gear levers, and obviously front and rear derailleurs, but never brake calipers.
You've apparently answered your own question then
