• 99.9% sure it was built by Jan van Dalen.
    Duell is his own company and I think he had/has no employees.

    I raced with him in the late 1970's and early 1980's.
    He was a good amateur (Gazelle amateur team), but didn't make it to the top ranks.
    Neither did I :-(

    But he made nice frame sets.

    I doubt that he ever raced this one...

    By the way, Jan's brother, Brady, does very nice paint jobs.
    Not only all the Duell frames, but a lot of other stuff as well.
