This is a lovely pair of Carl Zeiss Jena, Mini Binoculars. They are the Teleater, 3x Magnification Binoculars which work in the same fashion as a norml size pair. That is there is a wheel on the central stem to focus the left eye and the right eye can be fine focussed.

They carry the number 400671. They are made with a combination of brass and alloy. The alloy is used for the cast hinge and brass is used for the barrels and end caps.

There are some specks withing the elments of the optics, more so in the left hand barrel. Having said that the image is good and they focus well. They retain there original neck cord.

Please get in touch if you have any questions.
