Antique Decorative Four matching Copper Furniture Handles Ormolu 1900s Made in France

Four brass Matching furniture handles which are made in France in 1900s.
Each one measures each 1 15/16 in diameter or 4.7 cm in diameter approximately.
These handles swing on brass strip. The brass strip would be put through a hole in the front of the drawer. Unusual system I have rarely seen.
Some patina.
