Carl Zeiss Jena Teleram 18×50 binoculars. I am told these belonged to either my Grandfather or his Brother (my Great Uncle) and were used in WW2. I can neither confirm nor deny but am leaning towards them being from that era. They show wear and have 1 missing piece that I know of that appears to screw down the 1 eye lens. Please see pics. You may see something I don't. Other than that they seem to work well and come with the hard case. Could use a good cleaning. Didn't want to mess with what I dont know. Thanks for looking and feel free to contact me with any questions.
