Wind River 10x40 I.F. Roof Prism Binoculars (1 Viewer)

I have a pair of these in my collection, but am unable to locate any information on them. It would be much appreciated if the knowledgeable members of BF could advise the year(s) of production, phase coating (?), angle of view, if waterproof, original cost, and any other information.
Thank You, John

Appreciate any info you might have on these.

My uncle has one of these binoculars.

They are the early WindRiver models. They are not phase corrected. I believe the FoV is something like 270 ft @ 1000 yds though, I would have to ask him to verify that. Leupold also offered a center focus model as well as an 8x32. They still pop up now and again on ebay.

They aren't bad binoculars, especially for how old they are, but they are pretty much outclassed by just about everything out there now.

I retrieved missing technical information on an older Gold Ring 9x35 IF porro I have by just calling customer service. They took some information, including serial # and a day or so later e-mailed me all the information I needed.
