Can you guess what it is?

Believe it or not, it is an early attempt at a snow-machine. Time magazine had an article (Jan 1926) I found here: http://www.time.com/time/magazine/article/0,9171,728812,00.html?promoid=googlep

If I recall the historian's story correctly this is #12 of only 13 ever made (as they proved less than ideal).

That is awesome! Thank you for sharing, hardrock. I'm even more impressed with the design than before. I wonder how it would do getting up a steep hill? A conversion kit for a modern car might be a tad more difficult.
