Fabrique National d'Armes de Guerre, Herstal, Belgique, is a factory in Belgium that was founded largely by Ludwig Loewe & family of DWM and owner of Mauser. After the contract to supply the Belgian military with Mauser rifles was won, Belgium wanted to produce them in their own country. Ludwig Loewe was one of the shareholders of FN and one of his brothers was director at Vickers in England.
FN Herstal is like Colt, Hartford, Conn.
