Home Forums Hunting & Shooting Hunter's Campfire Collimation of vintage Zenith binoculars.

I put this in the optic forum but didn't get a response. I have an old pair of Zenith 7x50 prism binoculars. They have good glass but slightly out of alignment. A local camera shop said they send off binocs for Collimation but it runs around $100.00. I read that many binocs have their own set screws. I thought if anyone knows where the set screws are on these old Zenith type binoculars, could you tell me? These old Zenith look similar to those old world war II B&L binoculars.
