Former barnstormer turned airport manager Steve Wittman bought in 1934 an old used Curtiss D-12 engine and with it and the “built the smaller aircraft posible around a powerful engine” old formula he designed and built this astonishing artifact. Not a thing of beauty though -specially initially- with its original car-type radiator, short squared wing (it became shorter eventually) and lack of finesse. The Bonzo proved nevertheless to be a remarkably well mannered aircraft; at least between hazardous take-offs and landings. It took part in various of the classic Thompson Trophy contests with very honorable results.
Notice the innovative spring-steel landing gear. An innovation to be seen everywhere when Cessna made it their own

Looks like this one?
No, that is The Hosler Fury, built by Russell Curly Hostler. It competed in a few races, but always had problems. Curly, apparently, built a copy of the Curtiss pusher and taught himself to fly!
Gareth knew this one is the Fury: he was just asking why I see some likeness between the Bonzo and the Fury.
Something subjective I guess, but they shared a boxy nature, and barn door low aspect ratio wings….
