You see quite a few imported O/U's based on that action. Charles Daley, American Arms Co, Sears, and others I can't think right now of sold them. The trigger plates and overall quality seem to vary a lot. Yours looks like one of the nicer ones. I thought all were Italian, so I can't explain the French connection. All of the good ones I have seen have had double triggers. A few are 12 over .30-06.
I have a similar one made by Antonio Zoli but with 3" chambers and imported by, I think, American Arms Importers -San Francisco. I bought it for $400 bucks about 15 years ago. The guy let me test fire it behind the shop. Unbeknownst to me, he loaded it with magnum turkey loads and got huge enjoyment out of watching the thing wallop me. It was my first double and I still use it some. I shot 3 blue grouse with it last Saturday.
