FN contracted to build guns for John Moses Browning and later the company that bears his name. They also held licenses to produce various Browning patented firearms and market them in some countries outside the USA.
If it is marked Fabrique Nationale Browning patents, I doubt Browning USA will have the info. Browning is now a subsidiary of FN Herstal as are USRAC (Winchester) and FN Manufacturing LLC. Browning North America may have access to the Belgian files.
In life, strive to take the high road....It offers a better field of fire.
