For years, Old Plank has been purchasing antique French mailboxes, from the early 1900s -1930s. Cast iron and steel began to be used in the manufacturing process of mail boxes, beginning circa 1900 in France. Léon Mougeotte in 1899, passed a law, allowing their post office to supply steel and cast-iron boxes to companies and the general public. Very soon thereafter they became known as “Mougeottes” after their founder. This particular French mailbox was produced by Delachanal of Paris and was probably made before 1930.
