I still have the belt used on me growing up. It is hanging on the wall about six feet away. It had become to flexible for a really good belting any more. It was a 'hippie" belt. Double holes running the length and 2" wide.
Just purchased a "service" belt off Amazon 1.5" wide and between 1/8 and 1/4" thick, Dont buy a belt that is sewn together, it will come apart easily and not last long.
