This fabulous stylish Parisian jug was made by a French company Etains du Manoir. There is an Etains Du Manoir makers mark of a castle (Paris, France) on the underside of the metal base. Just below is the word Etain. (Etain is the French word for tin and is used in French pewter).
The jug was likely made in the mid-20th century and stylistically pertains to the 18th century.
There are some minor scuffs marks to the piece but is in overall excellent condition with a lovely patina that's been left undisturbed.
