I have heard that Jewish people like the F&P dishdrawers because in a Kosher kitchen you have to keep your meat an non meat dishes pots an pans separate.
I had this set in the late 70s.
Banging solonoids would make you jump. Very good machine. However it would tie a large load of shirts into a very tight ball. Dryer was very fast. No trouble for the 10 years I owned them.
