    Historical Review of Swift 804 Audubon Binoculars

    Historical Review of Swift 804 Audubon Binoculars

    Historical Review of Swift 804 Audubon Binoculars

    Hi guys: I doubt my comments will be of any worth. Since Jules has the bino in his possession, he knows that it has rubber eyecups.
