Wild ...but correct.
The De Monge 5.1 of 1921. Intended for the Coupe Deutsch and British Aerial Derby races but failed to compete in either. Converted from biplane to monoplane form with fatal results to pilot Count Bernard de Romanet due to flutter in the now unsupported upper wing.
Pictures and info from the late Tom Foxworth's The Speed Seekers 1975.
Back to you Mel.
