Ofuna Opera Binoculars 3 x 10

Very nice pair of vintage Ofuna Binoculars 3 x 10 made in Japan and comes with a leather carrying case. They measure 4 1/4" wide and 2 1/2" to 2 7/8" extended. They work great, the lens are clear and the adjustment screw is very smooth. The leather case is in excellent condition.
