I picked up a bike at the thrift store last week. Says St. Etienne on the headtube area. The downtube has a Francia decal on both sides. Now the odd part. At the top of the seatube is a Peugeot logo (lion?)
with Peugeot under it. I am of the opinion that it is a Peugeot but am not sure. Has Simplex deraillures and shifter, Mafac brakes . So Peugeot or St. E??? What you think?

Thanks
