Bachtold Bros "The Whipper" Belt Size

I bought a used Bachtold Bros brush cutter. Model name is The Whipper, model number is W24. It's a great piece of equipment, but I can't find a source for the drive belt. I only found a small piece of the belt after it broke, so I can't simply measure the carcass.



I've been all over the web and all I can find is the company is out of business and no one knows anything. I'm hoping the collective wisdom of this group will help resurrect a great machine.



Thanks all,
