This classical 7×50 Zeiss binocular was produced between 1961 and 1969, the particular sample here is from 1968. It is a typical example of the excellent large porro binoculars made by Zeiss (West)  in the 1960s and 1970s (at the same time and up until about 1990, Zeiss Jena was also producing very nice large porro instruments, see separate posts about “Carl Zeiss Jena Jenoptem 10×50”, https://binocular.ch/carl-zeiss-jena-jenoptem-10×50/  , “Carl Zeiss Jena Nobilem Super 8×50” https://binocular.ch/carl-zeiss-jena-nobilem-super-8×50/, and “Carl Zeiss Jena Octarem 8×50” https://binocular.ch/carl-zeiss-jena-octarem-8×50/). Another famous Zeiss Oberkochen model from that era would be the “Binocular of the Century” (see separate post about “Zeiss 10×50 Jahrhundertglas”, https://binocular.ch/zeiss-10×50-jahrhundertglas/).
