IMHO, I have seen this machine up for sale several times, pretty much, it is home made and a one of one, yes, just about every manufacturer started out as a home made machine.
fyi, mr g moose can confirm it, thiokol comes directly from the frandee snow cat, and not as a start up on it's own, it all started at Utah State Ag, and this one if anything could be a prototype of Frandee, if you are looking at it for as historic snow cat, do your home work...though it kinda looks like one of the snow cats at the 1950 Sun Valley, Idaho, snow cat trials, conducted by the soil conservation service.
this one is powered by a Ford, Model A 4 cylinder engine with its 3 speed transmission, pretty a bunch of mismatched parts........
