Uber Rare model 818. I have only seen photographic evidence of 2 including this one. Search for this model on Google and you will only find 2 references and 1 is on this very pair and can be found  on Cloudy Nights, the astronomy forum. Have looked for Swift documentation on this model,  including older catalogs and haven't seen them listed. Made in Japan with inspection sticker.

      If you are a collector of vintage Swift Japanese made binoculars, here may be your only opportunity, ever,  to purchase this very rare beast.

     The Bonus: They are excellent and the long focal length keeps false color to a mimimum. Razor sharp views and center focus. Protected with like new rubber armor skin and has all proper caps for lens.

     Condition: Like new with beautiful perfect coatings. Case is in very nice condition as well. Focus and diopter have super smooth motion with just the right amount of damping. Original box in great condition as a collector would demand.
