Hardware with the flashed-copper finish was the fad from about 1900 to 1920 or so. A copper plating was applied to a steel back plate and then sprayed or “flashed” with a black lacquer finish. Through the years this finish often wears off or is scrubbed off.
This pocket door pull looks un-used and like new. It may be old new stock. The finish is excellent. The pull was meant to recess into the pocket door so that the face of the plate is flush with the surface of the door which then slides into the wall.
The plate measures 7 inches long and 2 1/2 inches wide. The inset (for the fingers) measures 2 7/8 inches by 1 3/8 inches. The pattern is a beaded edge, which can be found also on passage-door back plates, door knobs, and key escutcheons.
