Indústria Nacional de Armas
Open-knowledge reference entry
Indústria Nacional de Armas (INA) was a Brazilian firearms manufacturer.
Background
In April 1940, the Brazilian Army officer Plinio Cardoso was in Denmark visiting the Dansk Industri Syndicat factory on an official mission, when the Germans invaded the country. Afraid that their submachine gun designs would fall into the hands of the Wehrmacht, the company handed the designs over to Plínio, who would return to Brazil and keep the designs safely away from Europe.
After the end of the war, the Brazilian officer returned to Denmark to return the designs, which began manufacturing the Madsen M-46 submachine gun soon after. In recognition of his work, the company granted him the rights to manufacture the weapon in Brazil.
Some models and first prototypes of the submachine gun would have been developed and adapted inside the IMBEL factory in Itajubá, in partnership with the engineer Euclydes Bueno Filho, who would join Plinio to found INA.
History
In 1949, the Indústria Nacional de Armas S/A was founded in the Utinga neighborhood of Santo André. During the 1950s and 1960s, INA supplied thousands of M950 and M953 submachine guns to the Brazilian Armed Forces, which remained in use from 1950 to 1972, mainly in the Brazilian Army, where it was the standard weapon of use during this period.
The first model of the INA submachine gun (M950) was heavily criticized by the military at the time due to its quality. The original design had been changed to the .45 ACP caliber in place of the original Danish design caliber, the 9×19mm Parabellum.
It also developed two models of revolvers and a small pistol based on the Czech CZ-45.
