This redwing 4 gallon water cooler is in very good condition and complete as any that I have ever seen. Not many have obviously survived like this one. The stamp reads: Red Wing Success Filter Manufactured by Red Wing Union Stoneware Co. Red Wing, Minn. U.S.A on the back is a stamp that reads: To insure best results Filter Blocks should be cleaned at least once each week. To Clean remove Block from Filter and brush same under stream of running water. Do not use brush for any other purpose as blocks are easily tainted. Thorough cleaniness is the chief requisite of any good filter. Front and back stamps are very bold with blue bands and decoative scrolling. Very good condition with no cracks chips or repairs. Measures 25″ Height and 12″ Diameter.
