Field Glasses or Binoculars Made in Occupied Japan Vintage

I dont know much about these beyond what is written on them. They have the age appropriate amount of scratches, etc and could stand to be cleaned up, but I have no idea the proper way to do that so I have let them be so as not to do any damage out of stupidity. I can see thru them just fine but whatever I am looking at looks kind of dirty like so I know the lenses need to be cleaned, replaced, something again I dont know. I did look at them and they look good when you look at the lenses but not as clear when you look thru them. Says crystal coated but I dont know what that means as far as these go. Comes with the original leather neck, carrying strap. Thank you for shopping, sharing and liking my closet today. I ship weekdays, no weekend or holiday shipping. Open to offers on all closet items.
