I have an apartment building in an old part of town, They are still using those refrigerators in some of the units. When they get too bad, they remodel the suite. Still working. They have counter units, Stainless, called Jamestown units (GE). Have some of the 4 wire GE burners in the electric built in cooktops. Damn things near indestructable. They have the GE pushbutton switches to control them, but I have to use dremmel to adjust them to fit.
As for the flair stoves, I have 4 customers who still have them. I think I'm one of the only one in my area who will work on them.
