I believe that Leitz made a 7X50 binocular called the MARSEPTIT from 1932 to
1962.  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
generally larger than roof prism ones.   If these binoculars are from the
60's they are probably pretty darn good.
