This plane is George Meyer's "Little Toot". George Meyer designed and built his Little Toot in a 6 year period between 1951 and 1957. The plane won the Mechanix Illustrated trophy for outstanding achievement in 1957 at the EAA convention.
I put together this brief history of the Little Toot. The Meyer family still operates Meyer Aircraft and still sells plans and parts for George Meyer's marvelous Little Toot.
