That's a Nervar Sport, but with TA chainrings. They also made the 5-arm 128 BCD Nervar Star, more like a Stronglight 93. I have to respectfully disagree with Harvey, I don't think there was anything even remotely second-class about these two Nervar models, nor for that matter about the Nervar 3-arm 116 BCD like the TA Professional.
The inner circle of the Nervar Sport was 128 BCD like the Star, just as the Stronglight 49D had a 122 BCD inner like the Stronglight 93. But like the Stronglight 49D, the Nervar Sport was available as a somewhat rare triple with a smaller inner circle. I just finished assembling a 50-42-36 triple chainring set for Nervar Sport.
