If you can still read the Geminiani labeling, seems to me you have a Geminiani….also, the less faded paint behind where a screwed on head badge used to sit screams Geminiani. As I have said, other than the references to brand, my "1965" Geminiani catalog is exactly the same as the Gitane catalog posted by GitaneUSA (mislabeled as 1967). I bought my catalog in France and I don't think many Geminiani bikes came over to USA, especially before bike boom so finding a Geminiani catalog is going to be tough. Knowing that MICMO produced both Gitanes and Geminianis in the mid-1960s, I would go read the catalogs posted by GitaneUSA as they have other 1960s catalogs posted as well. Their "1966" is also mis-dated as Anquetil did not ride a Gitane in 1966 so it is actually 1965 or earlier. As I stated above, your frame has the more finished seat stay cap, similar to white frame here and not the swagged and crimped finish seen contemporaneously on less expensive offerings as seen on blue frame here. I would thus look at the higher end bikes for the type of equipment offered. Because you have a Stronglight headset, I would focus on the Professional in the 1964 catalog or the Champion du Monde in the "1967" catalog (really1965). If the Stronglight is original, your fork tube was likely cut too short to properly fit a Campy headset.
