Greta chairs, sorta surprised mine have not been stolen yet (hell they steal American flags around here). I acquired mine from my wife's grandfather , when he passed 25 years ago. Don't know what they're called either, but if you see any at auction or anywhere for sale GRAB 'EM! They are the most comfortable chairs anywhere, the rust you see on mine is superficial and does not affect the comfort. One chair is sprung light and the other is really stiff, His & Hers? Ours are over 60 years old. Good luck figuring out what they call them. I would suggest looking at old Sears catalogs or Spiegal catalog, I will look in my 1950 Spiegal today........NGE
