The first version, the Ba.33 Serie 1, was a two-seat low-wing monoplane with external bracing between the wings and the fuselage.
It was powered by an 89-kilowatt (120-horsepower) de Havilland Gipsy III four-cylinder air-cooled inline engine.
[1] Ba.33s were the equipment of the Italian team for the International Touring Competition in 1932, with which also Winifred Spooner entered the contest.
However, two Bredas crashed on 23 August 1932, due to weak wing construction (one mechanic died bailing out), and Italy decided to withdraw all the Italian teams from the contest.
