it is about 4 years old and showing no sign of grinding away like some of the previous belts ... no cracks or sign of wearing out ... but then again ... it could be I had on the wrong reading glasses when I looked.

I think it came from an auto supply store ... went in with the old belt and out with this one. If I remember I also was able to get it an inch shorter because as I remember the old belts would nearly hit the adjusting limit when they were new. This is #505 here in Naples.
