I’m trying to figure out the artisan of this belt buckle, based on the hallmark. It’s a “TSN” stamp with the letters all connected. Then underneath there is some minus and plus symbols engraved and “Kingman” (I’m assuming the turquoise mine origin.) Any help would be greatly appreciated. Thank you!<img src="/upload
