There’s also the story of treadle sewing machines. I have heard (can’t find evidence) that after WWII we GAVE the Japenese the patents for treadle sewing machines. They are currently produced in China. They are junk (several reports; often purchased by Amish) meanwhile the Singer treadle sewing machines made in early 40’s are what anthropologists might call a “climax design.” Efficient manufacturing, easily repaired, durable.
One would think that with fears about energy one would hear more of the treadle sewing machine.
1940??? that's a youngster.
I have a 1896 Singer Sphinx model - my great grandmother's - in perfect condition. It sews better than any of the new machines I ever had. It's in the full cabinet with 4 drawers - here's the Sphinx model machine itself
this is how it looks closed
