Hello people, I can definitely need some help identifying a bicycle I bought recently!

A few days ago I had the opportunity to buy an old (don't know how old yet) french frame from the brand "Cottereau". There seems to be hardly any record of this company on the internet so I though maybe one of you has some information regarding the bike and its age. Any help is greatly appreciated because I want to try to keep the bike as original as possible staying true to its era.

Thanks in advance!
