    Wow. I’ve never seen a rear derailer quite like that! Fantastic. And how does that seat clamp work? It doesn’t look as if it’s squeezing anything. Thanks for sharing.

      It looks like it might be a bit of an optical illusion: the top of the clamp must be flush (or even slightly above?) the end of the seat tube?
      Anyway, Mark, yeah: Wow! It looks like it may even have its original finish, too!
      Just goes to show you, nobody does vintage like Europeans!
      What I’m wondering, is how does the front derailleur shift? I don’t see the opposing twin lever on the downtube, so I’m guessing the shifting mechanism is on the seat tube?
      Great OTS, Ákos!

        I’m sure the seat post clamp must just be an optical illusion, or magic.

        The front derailer is an earlier design. Instead of using a lever and cable, there is a steel rod on the seat tube, as you thought. To shift, you reach down and push or pull the rod. The thinking was that shifting the chain in the front was done infrequently. I think this design was pretty much phased out by 1960.
