Vintage Carl Zeiss Jena Jenoptem 8x30W binoculars, with original leather carry case.  The bridge, focus and diopter mechanisms work, and they give a good, clear image, free from double vision / distortion.  The optics are free from internal fractures and major scratches – they seem internally clean and fungus free, bar some minor misting when held against a strong light, and a little dust fragmentation.  There is a bit of paint scuffing to the metal barrel plates.  The case is in good condition, with minor scuffs.
