Vintage Igloo five gallon galvanized steel water cooler jug. The manufacturing label has apparently worn off but I believe it is an Igloo brand as is identical to Igloo coolers with the labels still affixed which have sold on ebay. No leaks. Spigot works. A little dirty and an odor on the inside lining, as this has been unused and in storage for a while. Filling it with hot bleach water once or twice and letting it soak should take care of the stains and odor.
Cup holder bracket has some oxidation as shown in one of the pictures. A slight ding on the bottom edge. The upper lip of the liner has pieces broken off but it still functions as designed and the lid remains nice and tight and comes on and off easily and as designed.
Several more pictures directly below.
