Nice save, Dave!
Gotta love vintage pairs. The Westy slant front twins are certainly iconic, and as John mentioned, worthy of a place in a collection.
Growing up in the 50s on the east coast, and moving almost every year for the first eight years of my life, I saw many Westinghouse washers everywhere we went. (And I made it a point to know what kind of washer everyone had!) They were very common, especially the design you have which I believe was produced from about 1948 through 1952. Westinghouse was the first to introduce a suspended tub to the market so the machine did not need to be bolted down and the first water level control.
They say washing performance was average and that was probably due to the detergents available at the time. (Detergents were just being formulated and introduced at the time, and most produced "mountains of suds" -- not good for tumble washing.) Extraction was average -- about 500 rpm, on par with Bendix and Whirlpool/Kenmore. I think rising was very good, with a long spray rinse and two deep rinses.
Westinghouse always produced at least two models, the BOL being a bolt-down model similar to what was found in the multitude of "Laundromat" coin-op facilities in the day.
They did tangle quite a bit, but had that nice drop down door to sit the tangled load on and untie it. That's what my mom did. She had a 57 MOL and loved her Westy slant front. Coming from using a wringer washer with six kids, the Westy was a big step forward in convenience and function and could do no wrong in her eyes. I liked it too -- with a window at my eye level to watch all the action.
I've heard said the change from tilted tub to horizontal in the late 50s improved washing performance and reduced tangling.
Good luck on the restore when you get to it!
