Set of 4 stove dampers made in Erie, PA by Griswold sometime in the 1910s. Set includes one each of the 4", 6", 8" and 10" sizes of the New American dampers. Dampers were made to go inside a stovepipe with the handle on the outside so it could be rotated to adjust the amount of air going through the pipe, which helps to regulate the fire. All are in unused condition and are in good condition with no chips or cracks. Some surface rust will be present as shown. Handles and spindles are present. A great set for display!
