Japanese WWII Navy 7x10 Binoculars & Case with Carrying Strap

Original era manufacture. The overall exterior condition is very nice, no issues with the rough texture frame paint, or the gloss black paint. It's original neck strap made of cloth and leather is also sound. The individual focus eyepieces work reluctantly, the lenses are murky but in proper collimation. The cloth covered case is sound with an original shoulder strap, and two yellow lens filters attached to the underside of the lid.
