This is a Belo Horizonte Brazilian revolutionary technical from 1930 constructed from either a wheeled tractor or civilian car and with a rotating turret, but no armament fitted. It has been substantially up-armoured and fitted with sliding armoured plates for the firing ports and driver's window as well as armour over the rear wheels, and at least 4-6 different improvised armoured vehicles were built by the Brazilian revolutionaries in Rio Grande do Sul, Belo Horizonte, Uberaba, Minas Gerais and Palmyra, now Santos Dumont.

​

Chevrolet's and Ford's were the most common chassis that appear to have been converted, and for comparison the main tank being used in the Brazilian military at the time was the Renault FT17 light tanks. This particular vehicle may have been based on a Thorneycroft with approximately 36-40 horsepower, and the vehicle had woeful acceleration due to the weight of the the vehicle alone, even before the armour and turret were added- The speed varied between 5 and 30 kilometres per hour, depending on the terrain and load, with the extra weight from the armour meaning that it was able to be overtaken by running men.

​

This vehicle was used between October 3 to November 3 of the 1930 Revolution, and was built for a possible fight with the Belo Horizonte military garrison but as far as I can tell did not see actual combat as few of the soldiers in that city fought against the revolutionaries by the time it was completed/deployed and it was instead used mainly for morale boosting and propaganda purposes. It's design seems rather heavily inspired by the WW1 Rolls-Royce Armoured Car. This particular example is not camouflaged, both other examples seem to be, and armaments were varied, with the majority of them being unarmed/rifle slits, while at least 1 was armed with a HMG and another with a flatbed where a 75MM field gun was placed.
