    Is there any way you can email the 55′ CDM pictures to me as I cannot blow them up to see them. I have a Bianchi bike just like yours I have had a very very hard time finding another like it until I saw yours. A 54’CDM is identical except for the “Bianchi” etched in the crank arms. Our bikes etchings match. I hope to restore it this year. It had been repainted black…but Celeste paint was found on the frame in some places so I will repaint to match.

    Thank you if you can help.

    With kind regards,
    Monty Pinson
