In france, starting in 1949, MORS has marketed a mini machine that looks like that. It has a drum that has two positions: low for washing (move back and forth), and for high-spin (fast car). It was sold on a metal stool and was draining by gravity. She would wash 3 kilos of dry cloth per load. You can see it in my website (gallery LES AUTRES)and it is working (wash and spin) in my video (www.lamachinealaver.com)
