Could this be the oldest snowmobile ?

[datasled]

From what i have found this predates alot of the other first snowmobile patents..

1913 i think according to the diagram it is leg powered so maybe its not in the same class?

Cant find anything that was built only the diagram,,

Sure would love to find one of these in barn!

Interesting but it not being engine powered and only leg powered shouldnt make a difference if it is a true patent,,But if it was machine designed to go across the snow in winter, I guess it could be considered a snowmobile of some sorts!
