Japanese Naval Binoculars 15 x 80

Japanese WWII 15 X 80 Toko Binoculars.
A large pair of Japanese ex-navy observation binoculars mounted on a vintage adjustable wooden tripod. The WWII marine binoculars with 4º incline eyepieces are marked '15 X 4º, TOKO, No. 1731'. These binoculars are predominately used for viewing the horizon, the optics give outstanding visual clarity and are equal to any similar modern binocular. The eyepieces can be adjusted for focus as can the interpupillary distance. The binoculars are a one-piece body casting for increased rigidity with exterior ports for charging the interiors with inert gas to expel moisture. They have been stripped and polished and are fully restored to original working order and give very good optical performance.

The measurements are without the tripod.

During the Second World War the Japanese manufactured a great quantity of large aperture binoculars. Out of all the countries involved in the war who were manufacturing such binoculars, Japan was the most prolific with Toko and Nikko being the largest contributors.
