This whitemetal casting represents the standard Reading S&T finial for tubular steel signal posts and dolls. Dimensions are approximately 13½mm high x 3½mm wide.
The finial should be painted white overall, and then the ball painted yellow if its post or doll carries only a distant signal arm. In all other cases, the ball should be painted red.
