What's interesting about this Spryte is the six axle arrangement. I've never seen that before and it looks like it is possibly factory. I've always liked to see special mods or variations of models on snowcats as it shows an industry that can easily change things up due to innovation, small production numbers and enthusiasm from the companies.
Did you see the Kristi in the background of the one picture, and another pic has a BR400? Another snowcat dreamland!
