For your consideration a vintage 1940's mixer/shaker. Made of metal with a lighted plastic front. Mixes the drink by shaking a cocktail shaker up and down. The knob on the side adjusts the speed.  Works but only with some help from my hand. See videos. I think it needs lubricated. Selling as needing serviced to operate properly.  Please examine pictures for condition. It measures 6" in width by 20" in height by 19" in depth and weighs about 20 pounds. Please check out my other items on Ebay. Thank you for looking.
