These are porro prism binoculars and were replaced by the Trinovid models which used the Uppendahl prism system (something like a roof prism). I have both older Zeiss porro prism binoculars as well as later Trinovid ones and I actually prefer those with porro prisms because they usually focus closer and more quickly, have larger exit pupils and they have a more 3D effect because the objective lenses are set wider apart. There isn't anything wrong with GOOD porro prism binoculars except that they are generally larger than roof prism ones. If these binoculars are from the 60's they are probably pretty darn good.
