I've never seen a '70s Gitane Tour de France with Huret dropouts but that doesn't mean that none exist. The bottle bosses could have been added later, but they wouldn't be original on a '70s French bike. The fish mouth stay ends are typical Gitane.

That fork looks nothing like a UO-8 fork, but it looks exactly like a '70s TdF or Super Corsa and the purple looks like an original Gitane color, as unworthy1 said.
