• Roto BB and R531, so it can only be an AA frame.
    I don't think there are AA-Specials with ROTO bracket shells, but I can be wrong.
    1970s I assume.
    Value in such a bad condition? Naahhh!
    Say, between 25 and 150 Euro.

    And serial numbers: could give a good indication, but none of the databases I have seen (2) are very reliable.
    The only reliable one is the handwritten book in the frame building department in Dieren. But even that one wasn't 100%.

    Give us some pics or browse through the old catalogues that JvS collected.
    Oh, you're lazy, aren't you?
