[1][2] The Argentine Army committed Dirección de Materiales to develop and build prototype models to supply the Force.

Project and construction were supervised by engineer Martín Reuter, working at the Esteban De Luca workshop in Buenos Aires.

The engine was entirely manufactured in Argentina at "Fundiciones Santini" factory while the crankshaft was built from a Siemens Martin iron piece.

One year later, the manufacturers requested Ministry of Economy permission to start serial production of the Ñandú but it was not allowed.

The Ministry alleged that Argentina was importing Willys MB vehicles from Belgium at US700 per unit, which was cheaper than producing the Ñandú.
