HENSOLDT WETZLAR Diagon 8X30

There seem to be two versions of Diagon's. This one, with smaller ocular lenses and it looks like without any coatings. That's why it is not particularly bright and let's say with average sharpness. However it has wide field of view and quite natural colours. Decent pair of binoculars. Old German school. This type has a serial number under a Diagon 8X30 markings and the other one, probably the newer version has a serial number beside the objective lens and a typical blue coating, visible on the ocular and objective lenses.
