It's a Sachs-Huret Duopar and is this the titanium model? The rear plate on the cage has a bluish tinge and I've never seen metal jockey wheels like this before.

I just noticed that there is something wrong. The flat nut that is over the black arm should be under it. The nut would have fallen off if you had left it loose enough to allow the arm to move. The arm doesn't need anything to hold it on. You'll see what I mean. See post #22.
