He's holding a pair of East German Zeiss (Jena) 10X50 center focus binoculars. They started trickling into he U.S. about then. Spectacular glasses at the time. Mine are not that pretty anymore.

B&L and Bushnell both had fine glasses at the time, but I'll bet ol' Werner had some "friends" in East Germany at the time.
