Russian Made Chinese DKSH Machine Gun Sights
This is a Russian made Chinese DKSH machine gun sight. This sight features several Chinese characters printed on the base next to the range markers. Additionally, this sight has an adjustable lever for the various distances that an object could be from it. These sights were most likely used on a machine gun that filled an Anti-Aircraft roll as there is a movable small plane atop the whole sights. This plane can be swiveled around in a circle to match the direction that a plane is flying. The sights come with a wooden storage mount as well.
