The brass sconces can be dated accurately as they have a British Registration mark of 219800 for the year 1893. The exact age of the Baccarat signed shades is unknown. The shades are a very loose fit and appear to be missing a part that locks them in / holds them down. Shades are 12cms in diameter, the swivel arms extend out 19.5cms + approx 3cms of shade overhang. They will be posted unassembled.
