Alright I didnt know which forum to post this in but the most knowledgable people are in this section thats for sure... Anyways I recentley was cleaning out my parents attic and found a really old Rangefinder In leather case and original box.

It is a Federal Long Range Rangefinder / Federal Instrument corp 114-06 rockaway blvd jamaica New York 11420

there is no year on it but has original directions. It has to be atleast 50 years old.

This is a crazy old school rangfinder hahait is pretty cool though.

If anyone knows anything about it please let me know. I have tried searching or finding a forum on antique rangefinders but no luck.
