FROM WIKIPEDIA

The Madsen is a light machine gun that Julius A. Rasmussen and Theodor Schouboe designed and proposed for adoption by Colonel Vilhelm Herman Oluf Madsen, the Danish Minister of War, and that the Royal Danish Army adopted in 1902. It was the world's first true light machine gun produced in quantity and Madsen was able to sell it in 12 calibres to over 34 countries. The gun saw extensive combat usage for over 100 years, with continued use in limited quantities worldwide into the modern day. The Madsen was primarily produced by Compagnie Madsen A/S.
