Two MB.90s were to take part in the Challenge International de Tourisme in August 1932, but did not show up although the first one, first flown in June, wears the event's tail stripes and number L2 underwing here. F-AMBO was displayed at the November 1932 Paris Salon, with a Renault 4Pei engine replacing its provisional DH Gipsy. In 1933 this aircraft was converted to MB.93 standard, but the MB.90 family was unsuccessful. Photo from: Dassault
