Jewelers Ring Finger Sizing Tool - Steel

Jewelers 26 position ring finger sizing tool probably from the 1940's or thereabouts, no markings other than sizes, believed to be made of punched steel (see last picture). Ya, you can buy a new plastic ring sizer but they don't last nearly as long as this will (has). No effort to clean it has been made. Images do a suitable job of representing the item.
