My own, on eBay: good condition Campy Pista bottom bracket marked 68- P-110 on the spindle. English threaded cups; all engraving in good condition. See pix at:
Came off my Raleigh Professional track frame. Since, once I can afford to get it built, I'll ride it on the streets, possibly in rain, I'll be putting a sealed unit in. Unit was original with bike. so I am told, so ti should date from 1973 or so.
