unsure Sears and Robuck not sure vintage

Original Vintage Sears & Roebuck Allstate swamp cooler. Nice condition for its age. Has some patina, may have some chips or scratches in the paint, cosmetic flaws but the cooler is in good used condition. Still has original cooler material inside. Has original spring loaded cord to rotate inside drum. Don't have original support arm, that is way the price is lower, easy to fabricate one.
Thanks Gary
