I just spent a half hour reviewing the photos I took of the factory museum.
There was nothing there that was a match to that, but there were a number of examples using similar handle materials, similar handle shapes, and a pommel that's not far off.
Just off the cuff, after reviewing those pics, I would say it's altogether possible Hoyt made something like that. There are plenty of of kind-of-exotic blades from that period, and more than a few using handle materials like that, and several with striped patterns. Even a few examples with similar guards.
I would definitely not exclude it from possibility.
