Vintage Emerson 16 Fan 79648-SD 3 speed, you can manually change the Oscillating position by moving the nut to different hole and by moving the dial where nut attaches. Wingnut will change your tilt position and lever on front will change the speed. This Fan may be old but works beautifully and can move some air. All is original but the white cord. Someone changed it before we owned it. Have had it for more many years. We let it run for several hours. It’s very quiet and doesn’t run hot. Very smooth running fan that puts out the air. Please see pictures for detailed description. Have any questions please contact me.
