Hiawatha Doodle Bug

Thank you for posting the photos. I have wondered what the original frame looked like.
I found mine buried on my property and later learned it had been cut down to be carried in a Cessna airplane. An older neighbor told me this.
The steering column was bent as if the bike left my mountain road and struck a boulder/tree and abandoned. The engine was corroded so badly it could not be salvaged. I put on a predator and the little bike is a screamer.
