This is a genuine set of Japanese WWII-era 7x71 binoculars, marked TO KO—the wartime code for Tokyo Kogaku Kikai (Tokyo Optical), a prominent optical manufacturer during the Second World War. The binoculars also feature the Tokyo Optical logo and are serial numbered No. 25442.
The body retains most of its original pebbled black plastic textured covering, though there is visible wear and some cracking in areas consistent with field use and age. The optics remain very clear, with only minor spotting present. Focus and adjustment knobs turn smoothly and function as intended.
The binoculars do not include a neck strap. Overall, considering their wartime use and age, they remain in very good condition.
