When I say extra Wide Angle (WA) bins I mean 70 to 75 deg AFOV, such bins are no longer made. These are bins of yesteryeas and to buy one, one has to go to ebay, so what good ones you suggest me to look for and which ones to overlook.
Regards.

I recently bought Nikon EII 10x36 bins new from a supplier in the UK. Over 7 degrees FOV. I was so impressed, I bought the Nikon EII 8x36 new from the same supplier. 8.8 degrees FOV, razor-sharp, bright as any others. Stunning bins, īcos I love wide FOV. Porros, not waterproof, "old-fashioned", but very light and a joy to use. They may be difficult to source but they are out there, and apparently still sold widely in Japan.
My first two binocular purchases were a Swift Nighthawk and a Nighthawk Mark I, both 8x40. Both have 499'FOV. The Nighthawk 7x35 is 578'. I still have and use the Nighthawks. Frankly what you get in extra FOV will not be as pleasing as Sanchos Nikon EII, and certainly not as good as the current Swift Audubon 8.5x44. What you get, in all of the older extra wide binoculars is eye relief that is unsuitable if you wear glasses. The wide FOV has zones in it. Center field is about 50%, then about the next 40% shows a little softness and the outer 10% shows quite a lot of softness. They are also not as bright as todays fully multi coated optics. Neither Swift can begin to hold its own with a Yosemite in image quality. My Swifts are good for the purpose they served, but you will be dealing with yesterday's technology. Those two Swifts are the only extra wide angle binoculars I have enough experience with to comment on.
