This is a pair of smaller than usual binoculars. They are marked “Carl Zeiss – Jena” on the left side, along with “DF 8X” (the lens power) and the serial number, “433914.” A small size such as this was most likely used by an army officer. It has no case, but the leather strap to carry them around one’s neck is in place. The leather wrapping on the exterior is complete and intact. The optics are clear and the binoculars are useable.
