These folding pocket Carl Zeiss 10 x 25B binoculars are in mint condition. They have a central focussing mechanism and a diopter adjustment. They were bought in 1982 in Vienna Austria and have been used very rarely indeed. They come with the original leather carrying case and lens covers and are in the original box and carboard sleeve. These binoculars have a 30 year guarantee which still has 4 years to run. The guarantee and user booklet are also included. In conjunction with the Zeiss Stereo Microscope Base (not included) these binoculars can be turned into a simple stereo microscope.
