Closest things ive ever found were these... First one says Parks Canada on it Second one says Canada, not sure on where it was used or by whom Last pair have US ARMY on them and are chevy I6 powered All owned by a guy who lived up in Hay River, NWT many years ago and took them with him when he moved 1000 miles south which is still 1000 miles north of here!
I really enjoyed watching that old film. I have to say that the concept is stellar and worked like a charm. Most great ideas are simple and this one follows the rule. I love that thing and if I still lived in my hill top house I swear I would find one and buy it. What a fun and perfect snow vehicle for the WI countryside!
