I'd say its probably just a colour variation,perhaps the guard hairs are just not as noticable because of their light colouring or maybe they dont have them because white guard hairs would be useless anyway?? I would be very carefull taking any part of a dead badger,as far as i know its illegal and could take some explaining if found in your possesion,especially being a hunter/shooter,they'd be quick to jump to the wrong conclusion
