The Federal Police of Buenos Aires ordered three armored vehicles from the Adolfo Bash firm, a local firm which had been building safes and armored vaults for banks and official institutions since 1882. Two of these were mounted aboard International B-series medium truck chassis and featured a rotary turret armed with a pair of Thompson submachine guns, which revolved over ball bearings, a third vehicle was ordered by the Police Department of Rosario. The third vehicle constructed over International A-series light truck reassembled a roadster of the period; but was fully armored and fitted with a two-way radio. The introduction of the larger Bash armored cars in 1933 led several foreign observers (including the US. Military Attaché) to conclude that the Army had transferred its Crossley model 1926 armored cars to the Federal Police; but this simply was not the case. The firm kept building armored cars for banks well into the late 1970s, many of them are still in use; but did not build any more armored vehicles for the Federal Police of the military.
