N.O.S. “Modernistic” Chain Stay.
These are still new in the bag, from the 1930’s. Made by the Chicago Specialty Mfg. Co., there is slight wear on the chrome of the one we opened for the photo. Solid brass with chrome plating, even the square nut is brass. Maximum thickness of sink is 1 1/4″, will cover holes up to 1 1/2″ in diameter. Why buy a reproduction when you can get the real thing?
