Looks to me like the rarer high end Gitane tandem from the mid-seventies, based on the shape of the stay caps and lateral tubes. It had 531 (single bike) tubing and was more than a bit flexible.

taking a whole lane. It has Shimano rear dropouts with a 122-mm spacing. The
fork has Brev. Campagnolo dropouts. The rear bottom bracket shell is 68-mm.
Supposedly it takes 27-inch wheels, but the distance from the dropouts to the
cantilever brake posts are 290-mm, which matches my beater 700-wheeled hybrid.
