Hi, I have a pair of ex army binoculars, no make on them unfortunately but they have lovely glass in them, 3D effect when viewing and nice and bright,made in japan and are rubber. .
As they are ex army, I have got no information on them and one thing I don't know is why both eyepieces barrels can be extended in and out about an inch or so ,I have no idea what this is for or does?, would anybody on the forum know?.
Thanks
