The first prototype of a truck suitable for all types of terrain was presented by Società Italiana Ernesto Breda to the Studies and Experiences Office in December 1936.
The outcome was positive and after some essentially aesthetic modifications, 48 were ordered by the ministry.
The spare wheels were keyed in neutral between the first and second axles, as on all Dovunque vehicles, to facilitate the overcoming of obstacles.
The Royal Army adopted it in the version with a reduced and more spartan cabin, the 'Breda 51' 'Colonial', used as a heavy artillery tractor for troops located mainly in Libya.
[2] In 1941 a model was produced with stronger chassis frame, the 'Breda 52', destined to become the basis for the later trucks.
