French prototype fighter design from 1939 that lost out to the Dewointine D.520. It is thought that the single SNCAO 200 flew in defence of the factory during the German invasion and may have shot down an enemy bomber. An order was placed for a small number of pre-production aircraft but these were captured whilst still incomplete by the Germans.
During development the design when through a number of changes and this model reflects the aircraft's configuration on the clearest 3-view diagram I found.
