      Yes, the link you provided leads to great photos of exactly the same binoculars!

      The most unusual thing about them is the aiming sight mechanism to pre-align the binocular position so you can find the flying object (tiny spot in the sky) with the higher power optics more easily. I imagine these were used mostly for spotter rolls and the exact ID of aircraft (IFF) as well as exact aircraft type (bomber, fighter, float plane, etc).

      Much thanks Guy!
