I gave a Classica, which I believe is the same thing as a Sierra to a friend yesterday. Today he brings it back to me, and while he was playing around with it apparently he pushed the transmission up in to the tube so far that the nib assembly won't screw in to it anymore. Anyone have any idea how to take it apart? I am mostly interested in salvaging the hardware at this point. Thanks!
If it helps here is a link to the assembly.
