The Journal Des Débats was an influential French newspaper that was published between 1789 and 1944. The following advertisements by Maison Lefaucheux were in various issues.
The earliest one I have acquired so far was from the August 18, 1839 issue. It lists the address of House Lefaucheux as 10, rue de la Bourse, This is the address that Casimir Lefaucheux worked out of from 1834 – 1835 and then again from 1845 to 1850.
