MG34 or MG42 50 Round Drum Magazine (Gurttrommel 34). The drum was capable of carrying a 50 round ammunition belt and could be mounted on the machinegun. The drum retains most of its original late war blue-grey coloured paint and shows some surface rust and scratches caused by usage. The box is nicely maker marked 'ddf' indicating production by the 'Lohmann-Werke AG' from Bielefeld. Nice example in good condition!
