The long, swaged and slightly wrapped seat stay tops are seen on some JA's and St. Etienne frames. Swaging also indicative of lesser steel in rear triangle. Some of the high end Anquetils were built by Carlton. I don't remember who else made Anquetil frames but it has been discussed here before. Enjoy your bike!
