I am a little late on this,but here is one that might be "off topic". I have a Campagnolo MTB bb that came to me on a Mercian road bike,(that might put it on topic), it has bb cups with seals attached and the sleeve is a one pice with Campy script and Italy on it also some traces of Campy grease .
happy trails
