beautiful work, Robert!
Interesting, ingenious design. Thanks for sharing your amazing, painstaking, detailed restoration work.
This design really successfully mimics front-loading wash action in a top-load format (the low water use and gentle scrubbing action.) And it doesn't knot the fabrics into ropes as modern impeller top loaders tend to do. As you mentioned, with today's detergents it must give excellent results. It's quiet as a mouse with the sealed lid closed. Really ahead of its time.
