well this is an odd duck: you have Campy DOs, Nervex pro seatlug abd BB shell, but what are those headlugs? A Nervex variant? And the BB threading: a JP unit, but is it ISO or FR? I'd say, give us the seat post diameter, name any markings on the bottom of that BB cup, and measure the OD of the 3 main tubes with a good caliper...otherwise, all I can say for now is that the forkcrown is one that Gitane and Peugeot both used...I don't think this frame is either.
