Japanese WWII binoculars 6 x 9.3 in case

Original Imperial Japanese Army binoculars with Japanese maker mark, lens serial number 87471 and power 6 x 9.3 degrees on the opposite side. Very good original condition with tinted lens covers and original leather neck strap. The binoculars come in the original rubberized canvas case with shoulder strap but missing the closing strap. As an extra accessory this comes with a lens cover also made of rubberized canvas material and in same condition as the case. This cover was fastened to the binoculars using leather straps which are present but are very fragile. This cover accessory is an extremely uncommon accessory.
