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.

It looks like you have all the important pieces. The should be a plastic plug that fits into the hollow mounting bolt, but it's just there for cosmetic purposes.
The jockey wheels look like 3rd party replacements -- Bullseye perhaps? But the upper pulley on the Duopar was fairly unique and I don't recall if Bullseye made a Duopar specific pulley for this. I'm not sure why you'd want them anyway -- the Duopar Ti pulleys used cup and cone ball bearings rather than the sleeve bearings typical of other manufacturers (even Campy and Dura-Ace).
