Hi everyone, my name is Jim. I'm from Long Island, NY. I need help identifying these Nikon 10x42 porros. Thanks in advance. (1 Viewer)

You have to be aware with virtually every porro (except the sealed ones like the Habicht and Fujinon) that the action of the focuser (which essentially pumps air into and out of the eyepieces as you work the focuser) can over time result in a light haze on the interior glass surfaces. I try to focus mine as little as possible to mitigate this: fortunately most of my birding is done at quite considerable distances and I don't have to big cycles of the focus wheel.

Nikon apparently will no longer service these, so you'll need to find a competent technician: fortunately a few of these are still in business. Besides Suddarth, Mountain Optics seems to get good reviews; you might want to make more detailed inquiries at the Cloudynights binocular forum.

Thank you for that bit of information, I was not aware of that. Will look into Mountain Optics as well & if I don't choose one of them will go to Cloudynights. Thanks!
