Well thats one of those that can be hard to pin down what it was actually badged as, it was a Tiawanese import that a few american outfits distributed and badged as their own. Scat cat- small engine distributors is one that sold them, in this brochure the closest is the "sassy" but as you can see it has angled forward bars, which are actualy removable, where yours is not.
gran prix was also another name/company, and I want to say they were just called "standard" through them.
they were imported to Australia as well and sold through Deltek
