We found these photos will researching the motorcycle-powered snow sleds we posted here recently. This was J. Armand Bombardier's first snow machine he built when he was 15 years old, you can learn all about it @ http://www.museebombardier.com/en/content/jab/biographie1907_1925.htm
He also mad many modified auto version using tracks and props through the 30's. In 29 he designed Tracks for a Model T and they are almost identical to the Snowmobile,Snow Flyer and Snow Bird. in 1931 he changed the track assembly to one drive wheel(duels on each side 30x3.5) and added 4 smaller bogie wheels for the belt tracks
to ride on. He played with these larger units until 1957 when he turned to the Snow Scooter Or
Ski-doo Model SK-60. Very interesting history.
Information from personal research and from a very interesting book called AS THE SNOW FLIES
by The Ingham Family,published in Canada ,(copyright 2000)I have no connection with them.
I have two Kinner R-55 engines that were used in snow sleds in Canada.
I would love to see a picture of a kinner powered sled
