These (trials?) bayonet knives, made in Turkey, are intended for the AKM machine guns obtained from Germany after its union. The bayonets were produced in limited number / only a few hundred pieces / in the state enterprise "Mitas Makina" in the city of Gaziantep (Mitas Gaziantep Makina Imalat San. Tic. A.S.).
The production was discontinued in 1999.
