I have one Ultegra BB 6500 (70, 36x24T, 109.5) New never used, dirt cheap (10usd), there's a catch, I don't have the non drive side shell (I have one but it's english threaded so therefore useless for an italian threaded BB). Let me know if you're interested (if you have an old one of those you could take the shell from that one, everything else is there in NOS condition).
