I messaged them to ask if they knew what size tires and model of fender and the answer was the tires were 2.25" Thunder Burt's and a Hanjo fender. I can see that the tires are Rocket Ron's and I can't find a hanjo fender that wide that was available around the time of this photo.
The goal for my new appaloosa is to do a 2.1" tire with fenders which from this photo looks possible if I can find the right fender.
Thanks in advance for your help!
