Remarks:

The “Pizar” by Kern came in sizes such as 8×30 or 6×24. A classic well made Porro binocular of the 1950s from quality producer Kern in Aarau, Switzerland, who supplied both the civil as well as the military sectors with various sizes of binoculars. At the time, 6×24 and also 6×30 used to be quite popular formats. The Kern binoculars were held in high esteem, competing with the likes of Zeiss and Leitz.
