Norge did make a bolt down
Actually, Norge's very first automatic washer was a bolt down. It was a front loader and only produced for about a year or so before their top-load, non-bolt down line was introduced.
Westinghouse also made a BOL bolt down machine for home use, similar to their coin-op washers that were produced well into the 60s, maybe beyond.
The Launderall/Horton top load H axis machines were bolt down too.
I think Beam may have made a bolt down agitator automatic for its customers like Western Auto, Gambles, etc. under the names of Wizard, Coronado and such. Not positive, but I've seen ads for round machines that look like a wringer washer without the wringer.
