That the shaft itself isn't bright and shiny leads me to believe, as others have said, that it didn't have a tight fit with the drum so was constantly moving a little which eventually fatigued the shaft to the point of breaking off. During my years as a prototype machinist, we would do districtive stress-testing and this type of break looks to be of the type described.
