How would I know that I have an Oberwerk HK 25x100 binoculars and not an Oberwerk FB 25x100 binoculars by just looking at them?

Thanks to you all

Hope you can pick up a pair soon. I really enjoy mine.

Any experiences / comments on Levenhuk 70mm Brunos? Commercial reviews are positive.

Wondering how these compare to Obie Deluxe 15x70s.

Levenhuk are on the same level of quality as the standard mass produced ones.
Oberwerks will have a higher level of quality.
