AFAIK, the DuoPar was only available in two versions; the Titanium body and cage one, and the steel body/cage "Eco" version. The titanium one has a distinctive grayish cast to the metal, and is non-magnetic. Here a picture of both, with the Ti one on the left:

The Ti version also has ball-bearing pulleys vs plain sleeve pulleys on the Eco model.
