I recently aquired (legally, for free) a pair of binoculars that are really old. Unfortunately, I know absolutely nothing about them. Could someone who is perhaps a bit old than I please give me some info on these. The binoculars have a markings on the top and bottom that read "The Conestoga Corporation, Bethlehem PA, USA. Model number FG-66. Made in the USA

Thanks,
Doren
