Are ball bearing pulleys a sure indicator of titanium? That is, assuming b-bearing pulleys weren't swapped into the non-titanium Eco.

The original Duopar had a titanium body and cage plates, with ball bearing pulleys. The Eco version, released about a year later, was identical except the body and cage plates were steel, and the pulleys were plain sleeve bearings (like Campy and most others). In the early 80s, Huret was bought by Sachs, and the labeling on the body was changed to "Sachs/Huret" reflect this. AFAIK, nothing else changed, and both the titanium and steel versions were still available.
I suspect both your specimens are "Eco" models, but from different production years. Take a magnet to the body -- maybe you're lucky and one of them is titanium.
