Marine spyglass of the USSR: ZTM4 20X50.

Functionality: the viewfinder lenses are clean on the outside, there are a couple of micro-specks of dust and small pieces of peeled internal paint on the inside of the front lens (all this can be easily disassembled and cleaned), but does not interfere with the overall view. The eyepiece is in excellent clean condition. Viewfinder visibility is good - without distortion, focusing operation when folded and unfolded is smooth and pleasant. The telescope consists of three sections, depending on the range of the object and the required optical segment.The plastic tube for storing the telescope has a broken bottom (it needs to be sealed).
