So I was at my Dad-in-laws yesterday, and he hands me three sets of binoculars, all in really great shape! They are all from the 70's, a 7x35 marked OPTEX, a 7x50 & a 10x50, both marked SEARS. All are also marked "Coated Optics", and the leather cases are not only in great shape, but all cases are the same and the various print is the same, so I think they are likley the same manufactuer, but what I am curious about is, how do these compare to current models?
