Steve, where did you get those adapters for the old trinovids?
Those are all from Jim White. That's the original binocular mounting system I went with in the late 90s...He may have been the pioneer of that kind of stuff. He made a great tripod head as well. Outdoorsmans used to sell his stuff and so did the lady that ran Coues Whitetail.com. Sadly he died a couple years ago.
