I finished a second Ball Head War Club. This is also made of maple, but it is about 19″ long and has a 3″ ball on the end. This style is often listed as an Algonquian style, but I can not find a definitive source for clarification.
The closest I found in a museum is identified as, “Ottawa, Native American, War Club, ca. 1825” While it is not exactly the style, it is close and would be from the same area.
